1 Understanding EdgeRouter VPN options: what you can show and how it’s used
EdgeRouter EdgeOS supports several VPN approaches. Each has its own use cases, strengths, and caveats:
– IPsec site-to-site and remote-access IKEv2: This is the workhorse for connecting two sites your home network to a remote office or a cloud VPC or providing a secure remote-access tunnel for individual devices. IPsec is widely supported and generally proven in mixed-vendor environments.
– L2TP over IPsec: A relatively easy-to-set-up remote-access VPN option that uses L2TP as the tunnel and IPsec for encryption. It’s common on many devices but can be slower and sometimes blocked by ISPs or NAT devices unless properly configured.
– WireGuard: A newer, lightweight VPN protocol known for speed and simplicity. Support on EdgeRouter has evolved over time. newer EdgeOS versions include WireGuard in some builds, while older builds may require workarounds or containers. WireGuard is great for performance on local links and remote access once set up.
– OpenVPN: EdgeRouter doesn’t ship a native OpenVPN server as of some firmware releases, but you can run OpenVPN in a container or on a connected device to terminate VPN clients or to bridge with the EdgeRouter network in some configurations. If your goal is straightforward “EdgeRouter shows VPN config,” IPsec and L2TP are usually the easiest to manage directly on EdgeRouter.
2 Prerequisites and quick-start checks
Before you start viewing or modifying VPN settings on EdgeRouter, gather these basics:
– Administrative access to EdgeRouter SSH or local console, plus a web UI login
– The device’s current EdgeOS version and model ER-4, ER-X, ER-LITE, etc.
– Your VPN topology: remote peer IPs, pre-shared keys PSK or certificates, and the local/remote subnets you intend to reach
– For remote-access users: the user credentials or certificates you’ll issue to clients
– Basic network setup: LAN subnet, WAN interface, and any NAT or firewall rules that will interact with VPN
3 How to view VPN configuration and status on EdgeRouter
There are two primary ways to view VPN config and status on EdgeRouter: via the CLI and via the web UI. Here’s how to do both, with practical commands you can run.
A CLI: quickly inspect configurations and live status
– SSH into your EdgeRouter or access the local console.
– To view the VPN-related configuration, you can search the configuration for vpn blocks:
– show configuration commands | match vpn
– To see live IPsec status and tunnels, use:
– show vpn ipsec sa
– show vpn ipsec ike-neighbors
– show vpn ipsec overview
– For L2TP remote-access details if configured:
– show vpn remote-access
– If you’re using WireGuard on supported EdgeOS builds:
– show ipv6 wireguard status if you’re using IPv6
– show wireguard
– To back up or inspect the exact CLI commands that make up your VPN setup, you can export the current configuration:
– show configuration commands | no-more
This will print the full set of EdgerOS “set” commands that build your VPN configuration. Copy it to a file for backup or to apply on another EdgeRouter.
B Web UI: visual inspection without the CLI
– Log in to the EdgeRouter Web UI.
– VPN configuration is typically under: VPN > IPsec or VPN > VPN Server for remote-access options and VPN > L2TP.
– In IPsec, you’ll see sites/peers, ike-group and esp-group settings, pre-shared secrets masked, and the active status of tunnels.
– In L2TP, you’ll see user profiles, pre-shared secrets, and tunnel status.
– For WireGuard, look under the VPN or Firewall sections depending on firmware to confirm interface configuration, peers, allowed IPs, and status.
Notes on what you’ll typically see:
– IPsec: ike-group, esp-group, site-to-site peer blocks, local and remote gateway addresses, pre-shared secrets masked in the UI, key lifetimes, and proposals.
– L2TP: remote-access profiles, pre-shared secrets, and tunnel status.
– WireGuard: interface name, private/public keys, peers with allowed IPs and endpoint, listening port, and current connection status.
– OpenVPN: if you’re using a container or a connected appliance to terminate OpenVPN, you might not see a native EdgeRouter “OpenVPN server” entry—your external OpenVPN gateway would be shown elsewhere. In that case, EdgeRouter’s role is routing/NAT.
4 Viewing vs. exporting: how to copy or backup VPN configurations
Copying or exporting is handy for backups or duplicating a setup on another device.
– From the CLI, you can generate the exact CLI commands that reconstruct your VPN setup:
Copy the output and save it as a backup file, or paste into a new EdgeRouter to apply the same VPN config.
– Web UI: while you won’t get a single export file, you can manually copy the settings IKE groups, ESP groups, peer configurations and re-create them on another device. For more automation, script-based management using the EdgeOS API can reproduce configurations, but that requires some scripting and API access.
5 Example scenario: IPsec site-to-site between EdgeRouter at your home and a partner network
This is a common, robust use case. Here’s a practical walkthrough high level, with concept steps you can adapt. exact CLI blocks may vary by firmware. The goal is to illustrate what you’ll configure and then show how to view it.
– Local network: 192.168.1.0/24
– Remote network: 10.10.0.0/16
– Local EdgeRouter WAN: your home public IP
– Remote EdgeRouter/public IP: 198.51.100.10
– PSK: yourStrongPSK123
– IKE group: default or standard AES256 with SHA256
– ESP group: AES256-SHA256
– Key lifetimes: 3600 seconds for IKE, 3600 for ESP
High-level steps:
– Define IKE and ESP proposals:
– IKE: aes256-sha256, group 14 2048-bit DH
– ESP: aes256-sha256
– Create the IPsec peer remote gateway with the PSK and the IKE group
– Add a site-to-site tunnel entry with local and remote subnets
– Ensure firewall/NAT rules allow VPN traffic and the correct traffic between the two subnets
– Test with ping across subnets, then verify with show vpn ipsec sa and show vpn ipsec overview
– If you need to re-run this on another EdgeRouter, export and apply the exact set commands
6 Troubleshooting tips: common problems and quick fixes
– VPN tunnel not forming:
– Check that the PSK matches on both ends
– Confirm the public IP addresses and DNS names are reachable no NAT misconfigs
– Verify IKE and ESP proposals match on both sides
– Check firewall rules, ensuring VPN ports are allowed UDP 500 and UDP 4500, and ESP protocol 50
– VPN tunnel drops intermittently:
– Review keepalive or dead peer settings
– Confirm stable internet and low jitter on both ends
– Remote access VPN users cannot connect:
– Check authentication method PSK vs. certificates and user credentials
– Confirm server-side radius/LDAP integration if used
– Ensure routing rules allow client subnets to reach LAN subnets
– Performance issues:
– Check MTU and fragmentation VPN often struggles around 1400-1500
– If hardware supports it, enable AES-NI and consider upgrading firmware for better WireGuard performance
– For IPsec, verify crypto settings are not overly heavy for your hardware
– OpenVPN workarounds:
– If you need OpenVPN, consider running it on a separate device in front of EdgeRouter or inside a containers environment, and route through EdgeRouter. Native OpenVPN server configuration on EdgeRouter can be limited depending on firmware.
7 WireGuard on EdgeRouter: what you should know
– If your EdgeOS version includes WireGuard support, you’ll configure a WireGuard interface, add peers, set allowed IPs, and define routes. This can yield higher throughput with lower CPU load on supported hardware.
– For remote access, you’ll create a peer configuration for each client, share public keys, and assign allowed IPs e.g., 10.0.0.0/24 or a smaller per-client subnet.
– For site-to-site, configure the WireGuard peer on both ends, with a dedicated subnet to avoid conflicts.
8 OpenVPN on EdgeRouter: approach and alternatives
– OpenVPN isn’t always natively exposed as a built-in server in EdgeRouter firmware. If you need OpenVPN access, you have two practical options:
– Run OpenVPN in a container on a connected device e.g., a NAS or a small Linux server and route VPN traffic through EdgeRouter
– Use a dedicated OpenVPN-capable device at your network edge and use EdgeRouter for routing only
– If your goal is simply to view VPN configs, IPsec and L2TP are typically easier to manage directly on EdgeRouter
9 Firewall and NAT considerations for VPNs
– Always ensure your firewall rules permit VPN traffic e.g., the ports used by IPsec and L2TP, as well as the IPsec ESP protocol
– Set appropriate NAT exemptions so VPN traffic isn’t NATed back to the public IP in a way that breaks the tunnel
– When using remote access VPNs, ensure client subnets don’t overlap with your LAN subnets to avoid routing conflicts
10 Security best practices and performance considerations
– Use strong authentication methods PSK with long random strings, or certificates where supported
– Keep EdgeRouter firmware up to date to benefit from security patches and performance improvements
– For remote-access users, consider disabling split tunneling if all traffic should go through the VPN for security
– Regularly review VPN logs and enable verbose logs only when needed to avoid performance impact
– In Canada, where privacy and data integrity are important, ensure you have a documented VPN policy and understand how your traffic is handled by your chosen VPN setup or provider
11 Practical tips for reliability and maintenance
– Schedule routine configuration exports copy of “show configuration commands | no-more” to back up VPN settings
– Maintain a small internal subnet plan to minimize routing conflicts across multiple VPN tunnels
– If you’re hosting a site-to-site VPN in a small business setup, consider a secondary EdgeRouter as a failover or keepalive path
– Test changes during a maintenance window, especially if you rely on VPNs for remote workers or critical services
12 EdgeRouter compatibility and model considerations
– Newer EdgeRouter models with the latest EdgeOS builds generally offer better VPN features and faster processing, especially for WireGuard
– If you’re upgrading, verify that the new firmware supports the VPN protocols you rely on IPsec + WireGuard vs. OpenVPN
– For home or small-business use in Canada, a mid-range EdgeRouter can handle IPsec site-to-site plus several remote-access VPN tunnels, assuming you don’t push too much traffic through the VPN concurrently
13 Tips for exporting, sharing, and documenting VPN configs
– Keep a documented “VPN portfolio” for your network: site-to-site details, remote-access users, subnets, PSKs, and expected traffic flows
– Use descriptive names for peers and groups e.g., “HQ_IPsec_IKEv2” or “Branch1_L2TP_Remote”
– Store export files securely, preferably in an encrypted vault or a password-protected archive

Frequently Asked Questions
Frequently Asked Questions
# How do I show VPN config on EdgeRouter?
You can view VPN configuration by using the EdgeRouter CLI: run show configuration commands | match vpn to see the VPN-related config blocks, and use show vpn ipsec sa or show vpn ipsec overview to inspect live IPsec tunnels. In the Web UI, check VPN > IPsec and VPN > L2TP to review current settings and tunnel status.
# Can EdgeRouter support OpenVPN natively?
EdgeRouter does not always include a native OpenVPN server in every firmware build. If you need OpenVPN, you’ll typically run OpenVPN on a separate device or container and route traffic via EdgeRouter, or use IPsec/L2TP for direct EdgeRouter VPN functionality.
# How do I test a VPN tunnel after configuring IPsec?
Test with a simple ping across the tunnel’s ends e.g., from a host on the local LAN to a host on the remote LAN. Then inspect EdgeRouter’s VPN status commands show vpn ipsec sa, show vpn ipsec overview to confirm that encryption and tunnel establishment are active.
# What’s the difference between IPsec and L2TP over IPsec?
IPsec is a suite of protocols providing encryption and integrity. L2TP is a tunneling protocol that can run over IPsec for secure transport. L2TP over IPsec adds an extra encapsulation layer but can be easier to set up for remote-access scenarios on some devices.
# Is WireGuard faster than IPsec on EdgeRouter?
WireGuard generally offers higher speeds and lower CPU usage compared to traditional IPsec on many platforms, but it depends on your EdgeRouter model and firmware version. If you have WireGuard support, it’s worth testing for performance.
# How do I view live VPN status in EdgeRouter UI?
In the EdgeRouter Web UI, go to VPN > IPsec to view tunnels, status, and active security associations. For WireGuard, check the WireGuard section if available in your firmware, and for remote-access VPN, check the Remote Access VPN area.
# Can I export VPN configuration from EdgeRouter?
Yes, you can generate the exact CLI commands that build your VPN setup with show configuration commands | no-more. Copy and save this for backup or re-creating on another EdgeRouter.
# How do I back up VPN settings for disaster recovery?
Regularly export the VPN configuration using the CLI show configuration commands | no-more and store the output in a secure backup location. You can also manually copy relevant settings from the Web UI for documentation.
# How do I troubleshoot VPNs when I’m behind CGNAT or carrier-grade NAT?
EdgeRouter VPNs can fail behind NAT if ports aren’t properly forwarded/opened, or if the remote peer can’t reach your public IP. Ensure proper NAT traversal settings, allow VPN ports through your firewall, and consider using a dynamic DNS service if your public IP changes.
# Should I use VPNs for all traffic or split-tunnel?
This depends on your security posture and performance needs. If all traffic should be secured, route all traffic through the VPN full-tunnel. If you only need access to specific resources, a split-tunnel configuration can improve performance but may expose non-VPN traffic to your ISP.
# How do I secure EdgeRouter VPN access for remote workers in Canada?
Use strong authentication certificates or long PSKs, restrict VPN users to only the required subnets, enable logging and monitoring, apply strict firewall rules, and keep firmware up to date. Consider using MFA for remote access if possible, and regularly audit VPN endpoints.
