What this guide covers and why you might show VPN config
VPN configs are the backbone of secure, private networking for both homes and businesses. For EdgeRouter users, there are two primary VPN paradigms: IPsec-based VPNs usually site-to-site or remote access and OpenVPN as a client or, in some setups, as a server. Being able to view and export these configurations is essential for:
– Backing up current VPN setups before firmware upgrades
– Migrating settings to a new EdgeRouter or another vendor
– Auditing security posture and ensuring PSKs, subnets, and peers are correct
– Troubleshooting connectivity by comparing current running config with a known-good copy
In practice, most EdgeRouter deployments leverage IPsec due to its tight integration with EdgeOS and robust performance across devices. OpenVPN remains popular for remote access scenarios or when interoperability with non-IPsec environments matters. The GUI makes everyday VPN tasks straightforward, while the CLI is your go-to for quick checks or bulk exports.
How to view VPN config on EdgeRouter using the CLI EdgeOS
Here’s a practical, hands-on approach if you prefer the command line. You’ll typically SSH into the EdgeRouter, enter configuration mode, and run a few focused commands to see what’s active.
– Step 1: SSH into your EdgeRouter
– ssh [email protected] replace with your device’s IP
– Step 2: Enter configuration mode to inspect running settings
– configure
– Step 3: View IPsec status and active tunnels
– show vpn ipsec status
– show vpn ipsec sa
– show vpn ipsec site-to-site peer
– Step 4: Inspect logical VPN objects peers, tunnels, and proposals
– show vpn ipsec ike-group
– show vpn ipsec esp-group
– Step 5: See general interface and routing context important for tunnel reachability
– show interfaces
– show ip route
– Step 6: Export or copy the current configuration for backup or migration
– show configuration commands
– exit
– optional copy the startup config to a backup file if your device supports it
– save
Notes and tips:
– If you’re debugging, pay attention to NAT traversal and local/remote subnet definitions in your VPN tunnels. A mismatch can stop a tunnel from coming up even if the peer is reachable.
– The exact command names can vary slightly by EdgeOS version, but in general you’ll be using show vpn ipsec commands to inspect the VPN state.
– For remote access VPNs, you might see user/PSK-based configurations here. for site-to-site, you’ll see peer IPs and tunnel mappings.
How to view VPN config on EdgeRouter using the Graphical User Interface GUI
Graphical configuration is a great way to quickly confirm what’s configured and to export a backup. Here’s a straightforward path to view and understand VPN settings in the GUI.
– Step 1: Log into the EdgeRouter web UI
– Open http://192.0.2.1 or the device’s management IP
– Step 2: Navigate to VPN settings
– For edgeOS that focuses on IPsec: VPN > IPsec Site-to-Site often under VPN
– For remote access configurations: VPN > OpenVPN if supported on the device
– Step 3: Inspect site-to-site VPN peers and tunnels
– Look for the peer address remote gateway, the IKE version, PSK or certificate usage, local/remote subnets, and tunnel definitions
– Step 4: Check status indicators
– The GUI usually shows tunnel state up/down, SA counts, and last handshake times
– Step 5: Review logs and diagnostics from GUI
– Logs or Diagnostics sections can help confirm why a tunnel isn’t starting
– Step 6: Export or backup the VPN configuration
– EdgeOS provides a configuration backup/export tool under System or Backup sections in many builds
– You can also copy the current GUI-generated configuration snippet to your clipboard for future reference
GUI tips:
– The GUI is often the fastest way to verify what’s configured without wading through text blocks in the CLI.
– If you’re migrating, use the GUI’s “Backup Config” feature to capture the running configuration, then restore it on another EdgeRouter.
How to export, backup, and migrate VPN configurations
Backups are your safety net when firmware upgrades or hardware migrations happen. There are a few reliable ways to preserve EdgeRouter VPN settings.
– CLI export text-based
– In configuration mode, use show configuration commands to print the current configuration as a set of commands you can reuse. Save this output to a text file on your computer.
– Running a backup copy of /config/config.boot also captures startup settings, which you can restore later.
– GUI export full backup
– In the EdgeRouter GUI, look for a “Backup Config” option often under System or Backup to download a complete configuration snapshot the file can typically be re-uploaded to restore the device to the same state.
– Partial exports VPN-specific
– If you just need VPN information, you can copy the relevant IPsec or OpenVPN sections from the running configuration CLI or manually re-create them in a new EdgeRouter during restoration.
Best practices:
– Maintain separate backup versions, with clear naming that includes the date and firmware version.
– Store backups offline or in a trusted backup system to protect against device-level failures.
– After restoring from backup, re-check VPN status and perform connectivity tests to confirm tunnels come up as expected.
Configuring common VPN types on EdgeRouter step-by-step guidance
Below are practical, real-world scenarios and the high-level steps to implement them. The exact command syntax can vary by EdgeOS version, so treat these as templates and adapt to your environment.
1 IPsec Site-to-Site VPN core enterprise and remote office connections
– Prepare: agree on remote subnet definitions local and remote networks, PSK or certificate method, and IKE/ESP policies.
– GUI approach recommended for many users:
– Go to VPN > IPsec Site-to-Site
– Add a new peer: specify the remote gateway IP, IKE version often v2, authentication mode PSK or certificate, and pre-shared key if using PSK
– Define tunnel 1: local-subnet and remote-subnet
– Choose encryption/integrity algorithms ESP group and PFS if needed
– Save, then test by bringing the tunnel up and pinging devices across the VPN
– CLI approach for automation or advanced users:
– set vpn ipsec site-to-site peer authentication mode
– set vpn ipsec site-to-site peer authentication pre-shared-secret
– set vpn ipsec site-to-site peer ike-group
– set vpn ipsec site-to-site peer tunnel 1 local-subnet
– set vpn ipsec site-to-site peer tunnel 1 remote-subnet
– commit
2 IPsec Remote Access VPN for employees or remote users
– GUI:
– VPN > IPsec Remote Access
– Enable remote access, configure user accounts, and define the authentication method PSK or certificate
– Verify client IP assignment, DNS settings, and split tunneling preferences
– CLI:
– set vpn ipsec remote-access user authentication mode
– set vpn ipsec remote-access sas-paths
3 L2TP over IPsec as an alternative remote access option
– Note: Some EdgeRouter builds support L2TP over IPsec as a separate path for remote access.
– VPN > IPsec Remote Access or L2TP settings
– Enable L2TP over IPsec, define PSK, and configure user accounts
– set vpn l2tp remote-access authentication mode pre-shared-secret
– set vpn l2tp remote-access authentication pre-shared-secret
– set vpn l2tp remote-access ipsec-for-l2tp enable
4 OpenVPN client or server on EdgeRouter if supported by your EdgeOS version
– GUI/CLI:
– EdgeRouter can support OpenVPN in some builds as a client or server. If your build supports it, you’ll find an OpenVPN section in the VPN menu or under Interfaces as vtun devices
– For client mode, configure the OpenVPN client with server address, port, protocol, and credentials
– For server mode, configure a local OpenVPN server, manage certificates, and define client subnets
– Tips:
– OpenVPN on EdgeRouter is less common than IPsec and may require extra packages or a newer EdgeOS release
– If you run OpenVPN on a separate device like a small VM or appliance, you can route EdgeRouter clients through that VPN for remote access scenarios
5 General tips for VPN tuning on EdgeRouter
– Use strong authentication: PSKs should be long and random, or switch to certificate-based authentication if supported
– Define clear local and remote subnets to minimize routing confusion
– If you’re behind NAT, enable NAT-Traversal NAT-T for IPsec
– Regularly update firmware to keep security fixes current
– Separate VPN traffic from your regular LAN traffic with appropriate firewall rules and routing policies
Verifying VPN connections and troubleshooting
Once you’ve configured VPNs, verification is crucial. Here are practical checks to confirm a healthy tunnel and troubleshoot problems quickly.
– Check tunnel status
– In CLI: show vpn ipsec status and show vpn ipsec sa
– In GUI: look for tunnel status indicators and active SA counts
– Validate connectivity across the VPN
– Ping devices across the tunnel from both sides to verify reachability
– Use traceroute to ensure traffic is taking the expected path
– Review logs and system messages
– Look for handshake failures, authentication errors, or routing mismatches PSK mismatches, incorrect subnets, etc.
– In GUI: System or Logs sections often reveal VPN-specific messages
– In CLI: tail -f /var/log/messages or equivalent while attempting a handshake
– Common issues and quick fixes
– PSK mismatch: re-enter or re-import the shared secret on both sides
– Subnet mismatch: ensure local-subnet and remote-subnet definitions line up on both ends
– Firewall rules: confirm that the necessary ports IPsec typically uses UDP 500/4500 for NAT-T and IP protocol 50 for ESP are allowed
– NAT issues: verify that NAT traversal is enabled if either side sits behind a NAT
– Performance considerations
– VPN throughput on EdgeRouter depends on CPU power and firmware efficiency
– Enable hardware acceleration if your model supports it
– For high-traffic locations, consider splitting traffic policies and ensuring the VPN tier can handle the expected load
Security, backup, and maintenance best practices
– Regular backups: keep multiple backups, with clear versioning and dates
– Firmware updates: test updates in a controlled environment when possible. ensure VPN configurations persist after upgrade
– Strong authentication: prefer certificate-based VPNs over PSK whenever feasible
– Segmentation: isolate VPN traffic with firewall rules and proper routing policies
– Monitoring: set up alerts for VPN tunnel status changes and unusual latency or packet loss
– Documentation: maintain a simple, readable log of what’s configured, who changed it, and when
– Redundancy: when possible, design redundant VPN paths to avoid single points of failure
NordVPN and EdgeRouter: how they fit
NordVPN is a consumer-grade VPN service aimed at personal privacy and access. It’s not designed to be the primary VPN backbone for an EdgeRouter-managed network. If you want a simple, always-on VPN for general outbound traffic, you could route devices through NordVPN at a consumer level or use a dedicated VPN router behind your EdgeRouter. For most EdgeRouter-aimed business or multi-site VPN tasks, IPsec remains the preferred method due to its reliability, performance, and native support. If you’re considering NordVPN as a quick testing or backup option, use the NordVPN link above to explore deals, but keep in mind EdgeRouter VPN configurations for site-to-site or remote access will typically rely on IPsec or OpenVPN client settings rather than a standard consumer VPN provider.
Practical testing checklist to ensure VPNs work as expected
– Confirm the tunnel state is up on both ends
– Verify traffic flow across VPN by pinging devices in the remote subnet
– Check MTU size and fragmentation issues if you see packet drops
– Validate DNS resolution for remote hosts when connected
– Ensure split-tunnel settings don’t inadvertently block desired traffic
– Re-check firewall rules and NAT rules related to VPN interfaces
– Test after firmware upgrades and after any network topology changes
