Key data and context
- The EdgeRouter line uses EdgeOS, with a CLI that resembles familiar router OS interfaces. If you’ve used Cisco-like or Juniper-like devices, you’ll notice similar concepts but different syntax.
- VPN adoption is growing worldwide as more remote workers rely on site-to-site and road warrior setups. In 2023–2024, the global VPN market grew at a double-digit pace, with market research estimating a multi-billion-dollar industry and continued strong growth into 2025–2027. This means more people are configuring and reconfiguring VPNs on devices like EdgeRouter, so knowing where your VPN config lives and how to display it matters more than ever.
- For home labs and small offices, EdgeRouter VPNs are appealing due to their robust CLI and reasonable performance, but features and options vary by model ER Lite, ER-4, ER-6, etc. and firmware version. Always cross-check your specific model’s commands against the official EdgeOS docs.

Understanding EdgeRouter VPN concepts you’ll see when you show the config
Before you run any commands, it helps to know what you’re looking for. EdgeRouter’s VPN sections are typically clustered under VPN, IPsec, and possibly OpenVPN, depending on what you’ve enabled. Here are the core concepts you’ll encounter:
- IPsec: The most common site-to-site and remote-access VPN method on EdgeRouter. Look for policies, proposals, peers, and tunnel interfaces.
- L2TP over IPsec: A classic remote access VPN, often paired with IPsec for transport.
- OpenVPN: Some EdgeRouter configurations support OpenVPN server or at least OpenVPN-related settings on certain EdgeOS versions. if you don’t see an OpenVPN block, you’re likely not using OpenVPN on that device.
- Phase1/Phase2: In IPsec, you’ll see Phase 1 IKE and Phase 2 IPsec SA settings. These include encryption algorithms, hash methods, DH groups, and lifetimes.
- Peer and tunnel definitions: The settings that bind the VPN to a remote network or user, including remote IPs, subnets, and authentication details.
Pro tips
- Always back up the current configuration before you make changes. A simple copy of the running configuration can save you hours if you misconfigure a VPN.
- If you’re diagnosing, capture the relevant VPN blocks IPsec or OpenVPN rather than the entire config to reduce noise.
Step-by-step: how to show VPN configuration on EdgeRouter
Below are practical steps you can follow in most EdgeRouter models with EdgeOS. If your CLI layout looks different, the concepts are the same—just adapt the exact keywords.
- Access the EdgeRouter CLI
- Connect via SSH or console to your EdgeRouter.
- You’ll often start at the operational mode and move to configuration mode.
- Show the full VPN-related configuration
- In EdgeOS, you can display the current active configuration with a command like:
- show configuration commands | include vpn
- show vpn
- If you want to see specific sections, use the targeted approach:
- show vpn ipsec — view IPsec VPN settings
- show vpn l2tp — view L2TP VPN settings if present
- show configuration commands | match vpn — search for VPN-related blocks in the running config
- To see live VPN status what’s currently active or negotiated:
- show vpn ipsec sa — IPsec Security Associations status
- show vpn ipsec status — summary of IPsec tunnels
- show log | match vpn — VPN-related log entries
- Interpret the key fields
- For IPsec, you’ll commonly see:
- peer address, local and remote networks, proposal encryption and hash, DH group, IKE version, and lifetime
- tunnel mode vs. transport mode less common on EdgeRouter
- For L2TP, you’ll often see:
- user credentials or certificate-based auth, depending on setup, shared secret, PSK
- the IPsec protection if using IPsec as the transport
- Keep an eye on the status blocks: “established,” “connecting,” or “down” will tell you if the VPN path is healthy.
- Export or back up the VPN config
- If you want to back up just VPN blocks, you can redirect the configuration portion to a file:
- save / config to a TFTP/USB or copy via SCP after displaying sections
- A full backup can be created with:
- show configuration commands > backup-vpn.conf
- For sharing or moving to another EdgeRouter, you can paste the VPN blocks into the target device’s configuration mode.
- Verify with a practical test
- If you’re dealing with a site-to-site VPN, ping a known host on the remote side:
- ping 10.0.2.1
- For L2TP or remote user VPNs, try connecting with the appropriate client and confirm traffic routes appear as expected in the routing table:
- show ip route
- Check the interface names for VPN tunnels that appear as separate interfaces e.g., eth0.20 for an IPsec tunnel or tun0 in some setups. Use:
- ip -brief addr
- show interfaces.
- If you don’t see VPN blocks
- Make sure the relevant service is enabled in the EdgeRouter configuration.
- Confirm you’re on a firmware version that supports the VPN feature you intend to view.
- Look for syntax changes in newer firmware releases and adjust your commands accordingly.
Checklist you can use as you go
- I know which EdgeRouter model I’m on ER Lite, ER-4, ER-6, etc.
- I know whether I’m using IPsec, L2TP, or OpenVPN
- I’ve found the right VPN section in the config IPsec/ VPN/L2TP/OpenVPN
- I’ve checked live status with show vpn ipsec sa or equivalent
- I’ve saved a backup of the VPN blocks I’ll reference later
- I’ve tested connectivity to verify the VPN works as intended
Specific commands by scenario
- Viewing IPsec VPN configuration
- show vpn ipsec site-to-site
- show vpn ipsec sa
- show configuration commands | match vpn | include ipsec
- Viewing L2TP over IPsec configuration
- show vpn l2tp
- show configuration commands | match l2tp
- Viewing OpenVPN-related settings
- show configuration commands | match openvpn

Real-world tips and pitfalls
- Consistency across devices: If you’re moving a VPN config from one EdgeRouter to another, ensure interface names and subnet definitions align. A mismatch in a local subnet can silently drop traffic.
- Updating firmware: VPN commands and syntax can change slightly between EdgeOS versions. If something doesn’t work, check the release notes for that firmware.
- Backups matter: A clean backup makes it painless to restore a working VPN if something goes wrong.
- Security hygiene: If you’re exporting configuration blocks, ensure they’re stored securely and not exposed to untrusted devices.
Performance considerations and data-driven insights
- VPNs add overhead. For IPsec, expect some performance hit based on your CPU, encryption algorithm, and tunnel count. In larger EdgeRouter deployments with multiple tunnels, you’ll want to monitor CPU load and VPN throughput using:
- show system resources
- As VPN usage grows, more remote devices will connect to EdgeRouter sites, increasing the need for stable tunnels and careful firewall rules. The industry trend shows VPN use increasing year over year, with growth driven by remote work, regulatory compliance, and privacy concerns.
- If you’re evaluating privacy and security posture, pair EdgeRouter VPNs with a trusted VPN provider for added client-side privacy when you’re away from the home/office network. The NordVPN deal linked above is one example of a reputable option you can consider.
Best practices for EdgeRouter VPN configuration and maintenance
- Centralize monitoring: Use a logging policy and syslog server to collect VPN events. This helps in quickly spotting issues when VPN tunnels go down.
- Use descriptive names: Name peers and tunnels clearly for example, “HQ_site_to_branch_ipsec” or “RemoteUser_L2TP” so you can quickly identify what’s what in the config.
- Schedule backups: Automate daily or weekly backups of your EdgeRouter config, including VPN blocks.
- Document routing: Make sure static routes or dynamic routing that depend on VPN tunnels are well documented so when tunnels flip, your routes don’t become stale.
- Test changes: Before applying changes to a production edge, test them in a lab environment or on a non-critical device.

- Encrypt sensitive data: When exporting, ensure the file is stored securely and access is limited.
- Use strong, unique credentials: For any remote access L2TP, OpenVPN use robust pre-shared keys or certificates and rotate them on a sensible schedule.
- Limit exposure: Only allow VPN access from trusted networks or IP ranges, and implement least-privilege firewall rules around VPN endpoints.
