Prerequisites and planning
Before you start, gather these details:
- Public IPs or domains for both endpoints Site A and Site B
- Local area networks LANs behind each EdgeRouter X, e.g., 192.168.1.0/24 and 10.0.0.0/24
- VPN encryption settings you prefer: AES-256, SHA-256, and a good Preshared Key PSK or certificate setup
- Decide who owns which network to avoid overlapping subnets
Network diagram example
- Site A: EdgeRouter X, LAN 192.168.1.0/24
- Site B: EdgeRouter X or another router with VPN, LAN 10.0.0.0/24
- VPN tunnel runs between the two public IPs or DDNS hostnames
Step-by-step setup overview
This section walks you through the core steps to configure a site-to-site VPN on the EdgeRouter X. We’ll use a common scenario: Site A 192.168.1.0/24 connected to Site B 10.0.0.0/24.
- Access the EdgeRouter X
- Connect to the router’s web UI: https://192.168.1.1 or your router’s LAN IP
- Login with admin credentials
- If you’re more comfortable with the CLI, you can use SSH and run the commands, but the web UI is friendly for most folks
- Confirm WAN and LAN settings
- Ensure the WAN interface has a public or reachable address
- Confirm the LAN network is set and won’t conflict with Site B
- Example: eth0 = WAN, eth1 = LAN 192.168.1.0/24
- Create the VPN pipeline IPsec
- The EdgeRouter X uses a VPN policy approach with a logical “tunnel” and a set of proposals
- You’ll configure: IKE version, pre-shared key or certificates, Phase 1 proposals, Phase 2 proposals, and the local/remote networks
- Define phase 1 IKE and phase 2 IPsec proposals
- Phase 1 IKE:
- Encryption: AES-256
- Hash: SHA-256
- DH group: 14 2048-bit or 19 AES-GCM, if available
- Authentication: pre-shared key
- Lifetime: 28800 seconds 8 hours or 3600 seconds 1 hour depending on policy
- Phase 2 IPsec:
- Encryption: AES-256
- Hash: SHA-256
- PFS Perfect Forward Secrecy: enabled group 14 or 21
- Lifetime: 3600 seconds 1 hour
- Specify local and remote networks
- Local network on Site A: 192.168.1.0/24
- Remote network on Site B: 10.0.0.0/24
- On the remote end, you’ll specify the inverse
- Enter the pre-shared key PSK
- Choose a strong, unique PSK and keep it secure
- Example: a long alphanumeric string with symbols don’t reuse across sites
- Apply and save
- Click Save, then Apply Config or similar
- If you’re using the CLI, you’ll push the configuration and commit
- Enable firewall rules as needed
- Ensure traffic between the two networks is allowed through the VPN tunnel
- Create firewall policies that permit IPsec-related traffic if your router requires it
- Test the VPN tunnel
- From a host on Site A 192.168.1.x, ping a host on Site B 10.0.0.x
- Check the status of the VPN tunnel in the EdgeRouter X UI
- If ping fails, verify:
- Phase 1/Phase 2 proposals match on both ends
- PSK matches exactly
- Local and remote networks don’t overlap
- NAT traversal settings if you’re behind NAT
Troubleshooting quick-reference
- Tunnel not coming up
- Recheck PSK and IP addresses
- Confirm that the public IP addresses you’re using are correct
- Ensure the tunnel policies on both ends match exactly encryption, hash, DH group
- No traffic across the tunnel
- Verify allowed subnets are correct
- Check firewall rules on both ends
- Confirm the VPN status shows “up” and not “stalled”
- Intermittent connectivity
- Consider longer IPsec lifetimes or re-key timing
- Check for unstable Internet connections on either side
Security considerations
- Use strong encryption AES-256, strong hashes SHA-256 or better, and a robust PSK
- If possible, consider certificate-based authentication instead of PSK for better security
- Keep EdgeRouter X firmware up to date to avoid vulnerabilities
- Consider enabling dead peer detection DPD and rekey options to maintain tunnel health
Tips and best practices
- Use non-overlapping subnets to avoid routing conflicts
- Document your configuration with a diagram and notes for future maintenance
- Regularly test the VPN after any network changes ISP changes, router replacement, etc.
- Consider a backup plan: a secondary VPN path or failover if uptime is critical
Common edge cases
- IPv6 considerations: If you’re using IPv6, extend your configuration with IPv6 counterparts or disable IPv6 on VPN if not supported
- Dynamic IP on the remote end: If the remote site has a dynamic IP, use a DDNS name and configure the EdgeRouter X to resolve it periodically
- NAT needs: If either side is behind NAT, ensure NAT-T is enabled so IPsec works through NAT
Advanced configuration options
- Dead Peer Detection DPD: Helps detect when the remote side is down and gracefully brings the tunnel down/up
- Redundant tunnels: Some setups benefit from a second tunnel with a different remote IP for resilience
- DNS handling: Decide how internal clients resolve remote site hosts split-horizon DNS if needed

Note: You must replace the placeholders with your actual values.
- Local WAN interface: eth0
- Local LAN: 192.168.1.0/24
- Remote WAN: x.x.x.x Site B public IP
- Remote LAN: 10.0.0.0/24
- PSK: YourStrongPSK123!

What is EdgeRouter X and why use a site-to-site VPN
EdgeRouter X is a compact, affordable router designed for small offices, home labs, and branch offices. It runs EdgeOS, a VyOS-like command line interface with a friendly web UI, and it’s capable of handling IPsec site-to-site VPNs with decent throughput for its hardware class. A site-to-site VPN creates a secure tunnel between two networks, so devices on site A can securely reach devices on site B and vice versa, as if they were on the same local network. That’s different from remote-access VPNs, where individual clients connect into a single network.
Key benefits you’ll notice with a properly set up EdgeRouter X site-to-site VPN:
- Encrypted traffic between locations, protecting sensitive data in transit
- Central management of remote sites without exposing internal subnets
- Ability to control routing and firewall rules separately for VPN traffic
- Cost-effective, easy-to-expand topology for small teams or home offices
Before you start, here are a few important realities:
- EdgeRouter X hardware is good for small-to-medium sites but has limited CPU cycles. Expect IPsec throughput in the hundreds of Mbps range under realistic loads. peak performance varies with encryption settings and firmware.
- IPsec site-to-site is typically more performant for fixed tunnels than client-based VPNs, and it’s more suitable for predictable traffic patterns between two known endpoints.
- You’ll need public IPs on both sides static is ideal, dynamic can work with a dynamic DNS helper and appropriate firewall adjustments.
Planning your VPN topology
A solid plan makes the actual configuration a lot smoother. Here’s how to think about it:
-
Define your subnets Edge web browser apk download guide for Android: download, safety, updates, and VPN tips 2026
- Site A LAN: 192.168.1.0/24
- Site B LAN: 192.168.2.0/24
- You can adjust these networks as needed, but keep them distinct to avoid routing conflicts.
-
Decide on the VPN type and authentication
- IPsec site-to-site with a pre-shared key PSK is common for small deployments.
- Choose an IKE IKEv1 vs IKEv2 group and ESP transformations you’ll support AES256, SHA256, DH group 14, etc..
-
Gather the public-facing details
- Site A public IP: a.b.c.d
- Site B public IP: w.x.y.z
- Remote peer addresses used by the EdgeRouter X at each site.
-
Routing strategy
- Route all traffic destined for the remote LAN through the VPN the tunnel is used as the gateway for that subnet.
- Ensure you’ve got firewall rules that allow the VPN traffic UDP 500, UDP 4500 for NAT-T, and ESP protocol 50 through the WAN, and then through to the internal networks.
-
High availability and failover
- If you’re dealing with critical traffic, consider a backup path or a second VPN tunnel, and plan for automatic failover or manual failover.

- Use strong PSKs and rotate them periodically.
- Keep EdgeOS updated.
- Disable unused services on the EdgeRouter to minimize attack surfaces.
Prerequisites and gear you need
- Two EdgeRouter X devices or EdgeRouter X S each connected to the internet with a public IP.
- LAN switches or access points behind each EdgeRouter X to service the local networks.
- A stable internet connection at both sites maintenance windows are ideal for changes.
- A strong pre-shared key for IPsec example: a long random string, not something easily guessable.
- Administrative access to both EdgeRouter X devices Web UI or SSH.
Optional enhancements:
- A dynamic DNS setup if you don’t have static public IPs, so you can maintain a reliable peer address.
- A dedicated firewall rule set to limit VPN traffic to only necessary subnets and ports.
EdgeRouter X: IPsec site-to-site setup steps
In this section, we outline a practical, copy-paste-ready style guide you can adapt. Replace the placeholder values with your actual IPs, subnets, and PSK.
Assumptions for the example:
- Site A EdgeRouter A LAN: 192.168.1.0/24
- Site B EdgeRouter B LAN: 192.168.2.0/24
- Site A public IP: 203.0.113.2
- Site B public IP: 203.0.113.3
- Remote peer on Site B: 198.51.100.2
- PSK: EdgeToEdge123
Step 1 — Access the EdgeRouter and enter configuration mode
- Use the CLI or Web UI to reach the configuration mode.
configure Edge vpn download 2026
Step 2 — Create IKE IKEv2 and IPsec proposals
- IKE group IKE-G1
set vpn ipsec ike-group IKE-G1 proposal 1 encryption aes256
set vpn ipsec ike-group IKE-G1 proposal 1 hash sha256
set vpn ipsec ike-group IKE-G1 proposal 1 dh-group 14
set vpn ipsec ike-group IKE-G1 lifetime 3600
set vpn ipsec ike-group IKE-G1 enable
Step 3 — Create IPsec ESP data plane proposals
set vpn ipsec esp-group ESP-G1 proposal 1 encryption aes256
set vpn ipsec esp-group ESP-G1 proposal 1 hash sha256
set vpn ipsec esp-group ESP-G1 lifetime 3600
Step 4 — Define the IPsec site-to-site peer on Site A
set vpn ipsec site-to-site peer 203.0.113.3 authentication mode pre-shared-secret
set vpn ipsec site-to-site peer 203.0.113.3 authentication pre-shared-secret ‘EdgeToEdge123’
set vpn ipsec site-to-site peer 203.0.113.3 ike-group IKE-G1
set vpn ipsec site-to-site peer 203.0.113.3 esp-group ESP-G1
set vpn ipsec site-to-site peer 203.0.113.3 local-address 203.0.113.2
set vpn ipsec site-to-site peer 203.0.113.3 remote-address 203.0.113.3
Step 5 — Optional Enable dead peer detection and other tunables
set vpn ipsec ike-group IKE-G1 dead-peer-detection time 30
Step 6 — Configure routing to send remote LAN traffic through the VPN Edge vpn mod apk safety, legality, risks, and legitimate Edge VPN alternatives for secure online privacy 2026
- You want traffic destined for 192.168.2.0/24 to go through the VPN. Create static routes or rely on policy-based routing as appropriate for your topology.
set protocols static route 192.168.2.0/24 next-hop - Note: Some EdgeRouter setups use the VPN tunnel as a logical interface and you’ll route through that interface. In practice, you’ll often set a static route that points to the remote network behind the IPsec peer.
Step 7 — Apply firewall rules to permit IPsec traffic
- Ensure your WAN-facing firewall allows:
- UDP 500 IKE
- UDP 4500 NAT-T
- IP protocol 50 ESP
set firewall name WAN_LOCAL default-action drop
set firewall name WAN_LOCAL rule 10 action accept
set firewall name WAN_LOCAL rule 10 protocol udp
set firewall name WAN_LOCAL rule 10 destination port 500
set firewall name WAN_LOCAL rule 20 action accept
set firewall name WAN_LOCAL rule 20 protocol udp
set firewall name WAN_LOCAL rule 20 destination port 4500
set firewall name WAN_LOCAL rule 30 action accept
set firewall name WAN_LOCAL rule 30 protocol 50
Step 8 — Save the configuration
commit
save
Step 9 — Verify and test
- Check the IPsec SA status:
show vpn ipsec sa - You should see SAs Security Associations up for the peer you configured. If not, review the logs:
tail -f /var/log/messages - Test from Site A to Site B:
- Ping a host on Site B: ping 192.168.2.10
- If pings fail, verify firewall rules, IP addressing, and route configuration.
Step 10 — Troubleshooting tips
- Double-check IPs and subnets: mistyping an address or swapping sites is a common pitfall.
- Ensure both sides use compatible IKE and ESP proposals encryption, hash, and DH groups.
- Confirm that NAT-T is functioning if you have NAT on your LAN side.
- Verify that the PSK matches on both sides and hasn’t been truncated or mistyped.
- Check that both EdgeRouter devices have their WAN interfaces allowed by firewall rules for IPsec traffic.
Step 11 — Testing with real traffic and monitoring Edge vpn mod apk 1.1.5 and safer VPN alternatives for mobile users 2026
- After the tunnel is up, generate some traffic across the VPN file transfers, streaming small data, or backups to confirm stability.
- Monitor CPU usage and VPN throughput. EdgeRouter X hardware has a finite capacity. heavy encryption can push CPU usage high, affecting other services.
Sample topology illustration for your planning:
- Site A:
- LAN: 192.168.1.0/24
- EdgeRouter A public IP: 203.0.113.2
- VPN peer Site B public IP: 203.0.113.3
- Site B:
- LAN: 192.168.2.0/24
- EdgeRouter B public IP: 203.0.113.3
- VPN peer Site A public IP: 203.0.113.2
This example is a starting point. Your actual commands will reflect your network addresses and the interface you’re using for internet access. If you’re behind double-NAT or you don’t have a static IP, you’ll add a dynamic DNS setup and adjust the remote-address target accordingly.
Firewalls, NAT, and performance considerations
- NAT and IPsec
- NAT-T NAT Traversal is commonly required if either side sits behind NAT. EdgeRouter X handles NAT-T, but you may need to ensure UDP 4500 is open and that NAT rules don’t interfere with VPN traffic.
- Throughput expectations
- EdgeRouter X is a budget router. Real-world IPsec throughput will be affected by facteur: CPU load, encryption settings, number of concurrent VPN connections, and traffic mix. In practical terms, you’re likely looking at several hundred Mbps under a clean path with AES-256 and SHA-256, rather than multi‑gigabit speeds. If you need sustained 1 Gbps VPN throughput, you may want a higher-end device or dedicated VPN concentrator.
- Monitoring and logs
- Regularly check the IPsec SA status and system logs to catch issues such as mismatched PSKs, dropped packets due to firewall rules, or unreachable remote peers.
Alternative approaches and convenience options
- If IPsec site-to-site feels too hands-on or if you need a quick lab test, you can set up a consumer VPN for individual devices to test connectivity, then replicate the route logic in the EdgeRouter for the site-to-site case.
- For more complex topologies or easier management, consider a small, dedicated VPN appliance at each site or a cloud-based VPN service where you manage fewer devices.
- If you’re testing with temporary labs, you may temporarily adjust the PSK and routes for faster iteration, but remember to revert to secure credentials for production.
Security best practices for IPsec site-to-site on EdgeRouter X
- Use strong, unique pre-shared keys and rotate them periodically.
- Keep firmware updated and patch as soon as new releases are available.
- Restrict VPN access in your firewall rules to only the IP ranges you actually need to reach through the tunnel.
- Use strong encryption AES-256 and a robust hash algorithm SHA-256 or better.
- Consider enabling Dead Peer Detection and anti-replay protections where supported.
- Regularly audit the VPN configuration to ensure there are no misconfigurations that could expose internal networks.
How to test performance and validate the tunnel
- Ping tests across sites: From a host in Site A, ping a known host in Site B.
- Traceroute to confirm that traffic traverses the VPN tunnel as expected.
- File transfers or large backups: Observe latency and throughput while the tunnel is active.
- Use network monitoring tools to verify uptime and health of the IPsec interfaces.
Frequently Asked Questions
Is Edgerouter X capable of handling site-to-site VPNs?
Yes, EdgeRouter X supports IPsec site-to-site VPNs, which makes it a good fit for small offices and home labs that need to connect two networks securely.
What type of VPN should I use for a site-to-site connection?
IPsec is the standard for site-to-site VPNs due to its strong security, compatibility, and performance on many consumer and SMB devices. You can opt for IKEv2 with AES-256 for a good balance of security and speed.
Do I need static IPs on both sites?
Static IPs are ideal because they simplify the peer configuration and reliability of the tunnel. If you don’t have static IPs, you can use dynamic DNS for remote reachability, but you’ll need to accommodate dynamic addresses on the peer configuration. Edge secure network 2026
How do I choose the right encryption and hashing settings?
AES-256 with SHA-256 is a common, secure default. For DH groups, DH Group 14 2048-bit is typical. You can adjust according to your performance and security needs, but ensure both sites agree on the same settings.
How can I verify that the VPN tunnel is up?
Use the EdgeRouter CLI command show vpn ipsec sa to check the Security Associations. Look for established SAs on the peer IP. You can also test by pinging devices across the tunnel.
What if the tunnel won’t come up?
Common issues include mismatched PSKs, mismatched IKE/ESP proposals, firewall blocks on the WAN interface, or incorrect remote addresses. Double-check the peer IPs, PSK, and proposals, and review firewall rules and NAT settings.
How do I route traffic to the remote network through the VPN?
Configure static routes on each site so that traffic destined for the remote LAN uses the VPN tunnel as its gateway. In EdgeRouter X, you typically add a static route pointing to the remote network behind the VPN.
Can I run multiple VPN tunnels to the same site?
Yes, you can configure multiple site-to-site VPN peers for different remote networks or backup tunnels. Ensure your routing policies and firewall rules distinguish the paths clearly and don’t create routing loops.

How do I handle updates and maintenance without breaking the VPN?
Plan maintenance windows, back up your configuration before applying changes, and test the VPN after any firmware update or significant change. Consider staging changes in a lab or test environment whenever possible.
What performance can I expect on EdgeRouter X for IPsec?
Performance varies, but with AES-256 and SHA-256, expect hundreds of Mbps in real-world scenarios. The exact throughput depends on hardware, traffic mix, and encryption settings. If you need higher throughput or more reliability, consider a higher-performance router or a dedicated VPN appliance.
Should I enable NAT-T for IPsec?
If either side is behind a NAT, NAT-Traversal NAT-T should be enabled to ensure IPsec traffic can traverse NAT devices. It’s commonly enabled by default in EdgeOS IPsec configurations.
Is it possible to switch to IKEv2 if I start with IKEv1?
IKEv2 is generally preferred for its efficiency and reliability. If your devices support IKEv2, migrating to IKEv2 is a good idea, but you’ll need to ensure both sites support the same IKE/IPsec settings.
Can I do site-to-site VPN with dynamic DNS?
Yes, dynamic DNS can be used if you don’t have static public IPs, but you’ll need to ensure the dynamic address updates on both peers are reliable and that the peer configuration references the dynamic hostname or updated IP address.

What’s the best way to document my VPN setup?
Keep a centralized log with all peer IPs, subnets, PSKs, IKE/ESP proposals, and firewall rules. Document the topology and keep a copy of your working configuration. Include notes on test results and any caveats you encountered.
Final notes
Edgerouter x site to site vpn setup is a practical, achievable project for connecting remote offices or branches securely. With careful planning, attention to subnets, and a solid set of VPN parameters, you’ll have a robust tunnel that can handle day-to-day corporate traffic and occasional backups. The EdgeRouter X is well-suited to this role when you approach it methodically: map your topology, lock down security, and verify continuously. If you hit walls, revisit the basics—IPsec peers, PSK correctness, and firewall/NAT rules are the usual culprits—and keep testing from both sides to confirm traffic is flowing as intended. And if you’re exploring consumer VPNs for additional tasks, don’t forget the NordVPN deal I mentioned earlier for quick, user-friendly protection.
