Prerequisites and planning for Edgerouter x site to site vpn setup

Before you start, gather these details:

EdgeRouter X on both sites with latest EdgeOS firmware
Public IP addresses on each site or dynamic DNS if you don’t have a fixed IP
Local networks Site A LAN, e.g., 192.168.1.0/24. Site B LAN, e.g., 192.168.2.0/24
The remote site’s public IP and its LAN range
A pre-shared key PSK for IKE authentication
Firewall access to configure VPN rules and to allow IKE UDP 500/4500 and ESP IPsec traffic
Optional: a management IP for each EdgeRouter to connect via SSH/GUI during setup

What you’ll achieve with this setup:

A secure, encrypted tunnel between two EdgeRouter X devices that lets hosts on one LAN reach hosts on the other LAN as if they were on the same network
Traffic between sites will traverse the public Internet securely, without exposing the payload
The tunnel can be reconfigured for different subnets or remote sites without changing your LAN addressing

Smart planning tips:

Use non-overlapping subnets for Site A and Site B to avoid routing conflicts
Consider adding a third subnet for management or a control network if you’re managing devices remotely
Plan failover and monitoring early: how will you detect tunnel down states, and how will you recover automatically?

Network diagram and mapping conceptual

Site A: EdgeRouter X public IP A → LAN 192.168.1.0/24 → hosts 192.168.1.x
Site B: EdgeRouter X public IP B → LAN 192.168.2.0/24 → hosts 192.168.2.x
VPN tunnel: IPsec with IKE and ESP between public IP A and public IP B
Tunnel endpoints: tun0 or ipsec0 depending on the firmware on both EdgeRouter X devices
Routes: site-to-site route entries so devices on 192.168.1.0/24 reach 192.168.2.0/24 and vice versa via the tunnel

This is a classic site-to-site VPN layout that works well for small to mid-size branch networks. As you implement, you’ll assign the local and remote subnets on each peer so traffic to the remote LAN flows through the VPN automatically.

EdgeRouter X IPsec site-to-site VPN: Step-by-step configuration CLI path

Below are the concrete steps for the CLI path. Replace the example IPs and subnets with your actual public endpoints and networks.

Define variables for clarity

Local subnet: 192.168.1.0/24
Remote subnet: 192.168.2.0/24
Remote public IP: 203.0.113.2
PSK: yourStrongPSK

Create IKE and ESP groups strong encryption defaults
set vpn ipsec ike-group IKE-GROUP proposal 1 encryption aes256
set vpn ipsec ike-group IKE-GROUP proposal 1 hash sha256
set vpn ipsec ike-group IKE-GROUP proposal 1 dh-group 14
set vpn ipsec ike-group IKE-GROUP lifetime 3600

set vpn ipsec esp-group ESP-GROUP proposal 1 encryption aes256
set vpn ipsec esp-group ESP-GROUP proposal 1 hash sha256
set vpn ipsec esp-group ESP-GROUP lifetime 3600
set vpn ipsec esp-group ESP-GROUP pfs enable

Configure IPsec peer remote site
set vpn ipsec site-to-site peer 203.0.113.2 authentication mode pre-shared-secret
set vpn ipsec site-to-site peer 203.0.113.2 authentication pre-shared-secret yourStrongPSK
set vpn ipsec site-to-site peer 203.0.113.2 default-esp-group ESP-GROUP
set vpn ipsec site-to-site peer 203.0.113.2 ike-group IKE-GROUP
set vpn ipsec site-to-site peer 203.0.113.2 local-address your_public_ip_A
Define tunnel parameters local and remote subnets
set vpn ipsec site-to-site peer 203.0.113.2 tunnel 1 local prefix 192.168.1.0/24
set vpn ipsec site-to-site peer 203.0.113.2 tunnel 1 remote prefix 192.168.2.0/24
Ensure tunnel is enabled
set vpn ipsec site-to-site peer 203.0.113.2 enable Vpn in microsoft edge: how to use a vpn in edge browser, setup, extensions, edge secure network, and privacy tips
Firewall and NAT considerations keep VPN traffic clean

Allow IPsec traffic on the firewall
Ensure that VPN traffic is not NATed improperly
If you’re doing NAT on Site A to the Internet, be mindful that VPN traffic between sites should bypass NAT

Routes and reachability

Sites should automatically learn routes via the VPN
If you need explicit static routes, you can add them example on Site A:
set protocols static route 192.168.2.0/24 next-hop 192.168.1.1
Replace next-hop with the appropriate internal gateway on Site A if needed

Verification commands live tunnel checks

show vpn ipsec sa
show vpn ipsec status
show log vpn

Test path traffic

From a host on Site A e.g., 192.168.1.10 ping 192.168.2.20
From a host on Site B e.g., 192.168.2.20 ping 192.168.1.10
If pings work, you’ve got working tunnel routing

Notes and tips:

If the tunnel doesn’t come up, double-check PSK, remote IP, and that both peers can reach each other over UDP 500/4500
Ensure your Internet firewall allows IPsec traffic
Some home or small business routers with dynamic IPs require a dynamic DNS setup on both sides to ensure peers can reach each other

EdgeRouter X IPsec site-to-site VPN: GUI method short, friendly path

If you prefer the Web UI, here’s a quick path that achieves the same result:

Open EdgeRouter X GUI and go to the VPN section
Create IKE Group: set encryption to AES-256, set hash to SHA-256, set DH group to 14, set lifetime to 3600
Create ESP Group: set encryption to AES-256, set hash to SHA-256, enable PFS if you want perfect forward secrecy
Add a new IPsec Site-to-Site Peer
- Remote Peer IP: remote public IP
- Local Address: your public IP
- Authentication: PSK. enter the pre-shared secret
- IKE Group: IKE-GROUP
- ESP Group: ESP-GROUP
- Local Subnet: 192.168.1.0/24
- Remote Subnet: 192.168.2.0/24
Save and apply
Confirm the tunnel status is “UP” and test traffic between subnets
Add necessary firewall rules to allow IPsec traffic and to avoid NAT on VPN traffic

GUI tips:

If you have multiple WANs, you may need to set the correct local-address on each peer
For dynamic IPs, consider using a VPN with a dynamic DNS service on both sides so the peers can always find each other

NAT, firewall, and security considerations for Edgerouter x site to site vpn setup

NAT: In a site-to-site VPN, you typically do not NAT traffic between the two internal networks. The VPN should handle private addressing and route the traffic across the tunnel. If NAT is interfering, adjust your firewall rules to bypass NAT for traffic between 192.168.1.0/24 and 192.168.2.0/24 through the VPN.
Firewall: Ensure you have rules that allow IPsec-related traffic UDP 500 for IKE, UDP 4500 for IKEv2 NAT-T, and ESP protocol 50 on the interface connected to the Internet. Then, permit traffic from 192.168.1.0/24 to 192.168.2.0/24 across the VPN tunnel.
Security: Use a strong PSK long and random and avoid default or weak encryption choices. AES-256 with SHA-256 and a DH group like 14 is a solid baseline for most small-to-medium deployments.
Redundancy: If you’re critical about uptime, you can add a second VPN peer as a backup path, though that adds complexity. For most home and small business deployments, one solid site-to-site VPN suffices if the Internet connection is stable.

Performance notes: Edge vpn download for pc

EdgeRouter X is a capable device, but VPN throughput depends on CPU load and encryption settings. In typical lab conditions with AES-256 and SHA-256, you might see VPN performance ranging from a few hundred Mbps to around 400 Mbps, depending on firmware, firmware optimizations, and other traffic. Real-world numbers vary, so expect something in the lower hundreds Mbps rather than full fiber-line speed if you’re running many services or watching heavy traffic on both sites simultaneously.

Troubleshooting common issues

Tunnel won’t come up:
- Re-check PSK, peer IP, and that there’s no NAT or firewall blocking UDP 500/4500 or ESP
- Verify that both sides can reach each other’s public IPs at all
- Confirm the local and remote subnets are correct and non-overlapping
Phase 1 IKE negotiates but Phase 2 IPsec tunnel fails:
- Verify ESP group compatibility and ensure both sides support the chosen cipher/hashing
Traffic fails to reach the remote LAN:
- Check static routes or ensure the traffic uses the VPN tunnel by default
- Look for “no route to host” messages on hosts, indicating missing routes
Intermittent tunnel drops:
- Check ISP stability and MTU-related issues. sometimes IPsec requires a different MTU to avoid fragmentation
- Confirm there’s no dynamic IP issue if you rely on dynamic DNS. ensure the dynamic DNS entries are updated correctly

Monitoring and verification commands CLI:

show interfaces
show ip route
ping from Site A to Site B’s LAN

If you bump into a persistent issue, steps that help the most are rechecking the PSK, confirming the public IP addresses, and validating that both sides can reach each other directly for example, via ping from EdgeRouter X to the remote device’s public IP. A systematic, step-by-step verification often reveals misconfigurations or subtle routing mistakes.

Performance optimization tips

Use AES-256 for encryption and SHA-256 for hashing as baseline. avoid older ciphers like 3DES that may be slower and less secure
Consider reducing the MTU if you experience fragmentation across the VPN tunnel
If you’re deploying a lot of traffic across the tunnel, ensure you’re not saturating the EdgeRouter X CPU. adjust QoS to prioritize important traffic
If you operate at higher speeds than your device can handle with the VPN, you may consider upgrading to a router with a more capable crypto engine or enabling hardware offload features

Security best practices for Edgerouter x site to site vpn setup

Regularly rotate PSKs and use unique credentials for different sites
Keep EdgeRouter X firmware up to date to mitigate newly discovered vulnerabilities
Monitor VPN logs for unusual activity. enable alerts if your system permits
Use strong authentication methods and avoid shared credentials across multiple VPN connections
Document your topology and the VPN configuration so you can recover quickly after hardware changes or outages

Practical testing checklist

After configuration, verify the tunnel shows as up in the EdgeRouter UI or CLI
From a host on Site A, ping a host on Site B and verify latency and packet loss
Test access to services across sites e.g., file shares, printers, internal apps to confirm end-to-end reachability
Verify that clients on Site A can reach Internet resources via the primary Internet connection and that VPN traffic prefers the tunnel when appropriate
Check logs for any IPsec or routing anomalies and correct misconfigurations

Frequently Asked Questions

What is Edgerouter x site to site vpn setup?

Edgerouter x site to site vpn setup is the process of creating a secure IPsec tunnel between two EdgeRouter X devices so devices on one local network can access devices on the other network through an encrypted connection.

Do I need a static IP to configure site-to-site VPN on EdgeRouter X?

Static IPs are not strictly required, but they simplify maintenance. If you have a dynamic IP, use a dynamic DNS service on both sides to ensure peers can always locate each other.

What encryption methods should I use for IPsec on EdgeRouter X?

AES-256 for encryption and SHA-256 for hashing are solid defaults. Use a DH group such as 14 for forward secrecy, and enable PFS if you want extra protection against future compromises. Edge vpn download: Ultimate guide to safe, fast, private Edge VPN download for Windows, macOS, iOS, and Android

How do I test that the VPN tunnel is up?

Check the EdgeRouter’s VPN status CLI: show vpn ipsec status and ping across the tunnel from hosts on each LAN e.g., ping 192.168.2.50 from 192.168.1.0/24. Use logs to identify if the tunnel is dropping or reestablishing.

What if the tunnel drops intermittently?

Intermittent drops may be caused by ISP instability, VPN keepalive settings, or MTU fragmentation. Try adjusting MTU to reduce fragmentation, and ensure your Internet connection is stable. Check IPsec SA lifetimes and rekey timing to minimize mismatches.

Can I have multiple sites behind EdgeRouter X?

Yes. You can configure additional IPsec site-to-site tunnels for other sites, but you’ll need careful subnet planning and more firewall rules to ensure proper routing and security.

How do I handle dynamic IPs on one side?

Use a dynamic DNS service on the side with dynamic IP, and configure the IPsec peer with the dynamic endpoint if the router supports dynamic updates. Alternatively, you can run a VPN hub-and-spoke configuration where hub endpoints use stable IPs.

How do I configure firewall rules for IPsec?

Allow IPsec UDP 500 and UDP 4500 and ESP protocol 50. Create a rule to permit traffic between the two LANs through the VPN and ensure NAT does not alter VPN traffic unless intended. The exact rules depend on your network’s policy and the EdgeRouter’s firewall zone layout. Disable edge secure network

What is the difference between IKE and ESP groups?

IKE Internet Key Exchange governs how security associations are negotiated how encryption keys are established. ESP Encapsulating Security Payload defines the actual encryption and integrity protection for the data being sent across the tunnel.

Can I test with a consumer-grade internet connection?

Yes, the EdgeRouter X works well with consumer-grade connections for site-to-site VPNs. Expect performance to scale with the inbound and outbound bandwidth. VPN encryption adds overhead, so you may see some reduction in raw throughput.

How can I monitor VPN activity over time?

Use the EdgeRouter’s log viewer and VPN status pages to monitor uptime, phase changes, and tunnel health. Regularly check for dropped SA security association or negotiation errors and adjust config as needed.

Are there any best practices for long-term maintenance?

Document every change, keep a backup of the running configuration, monitor for firmware updates, and test the VPN after any network changes or ISP maintenance. Schedule periodic reconfirmation of tunnel reachability and rewrite rules as networks evolve.
