What Edgemax VPN does for your network
EdgeRouter devices from EdgeOS are known for their versatility and price-to-performance ratio. A solid VPN setup can do several important things:
- Connect multiple office locations securely via IPsec Site-to-Site, creating a single, encrypted tunnel between sites.
- Enable remote worker access to your corporate resources with a dedicated VPN tunnel, improving security over public Wi-Fi.
- Segregate VPN traffic from regular traffic to improve security and manageability.
- Allow you to apply firewall rules and QoS specifically to VPN traffic so you can guarantee bandwidth for critical services.
Two of the most common use cases you’ll see with Edgemax VPN setup are site-to-site IPsec VPNs for linking two offices and client VPNs for individual devices or users that need remote access. IPsec remains the backbone for many business VPNs because of its solid security model, wide support, and compatibility with many gateways.
Prerequisites
Before you start, make sure you have:
- A compatible EdgeRouter running EdgeOS with recent firmware 2.x series would be ideal for latest VPN features.
- Administrative access to the EdgeRouter web UI or SSH/CLI.
- Static or dynamic WAN IPs for both gateways if possible. if you’re behind CGNAT, you’ll need workarounds.
- A plan for IP addressing and subnets to avoid overlapping networks e.g., 192.168.1.0/24 at Site A and 192.168.2.0/24 at Site B.
- A secure pre-shared key PSK or, for higher security, certificate-based authentication if you choose to deploy IKE with certificates.
- Basic firewall rules in place so VPN traffic is allowed you’ll refine them during setup.
- Optional: a managed DNS solution or dynamic DNS if your WAN IP changes.
If you want an extra level of convenience and protection for employees connecting in, consider a VPN provider with a reliable client option. For example, NordVPN often runs promotions and can be used on client devices alongside your EdgeRouter VPN setup. See the NordVPN offer linked in the introduction image for current deal details.
VPN options on EdgeRouter: IPsec vs OpenVPN
EdgeRouter EdgeOS supports several VPN approaches. The most common are: Download free vpn extension for edge: best Edge VPN extensions for privacy, speed, streaming, and security
- IPsec Site-to-Site: Great for linking two networks. It provides a secure tunnel between sites and integrates with routing and firewall rules on EdgeOS.
- OpenVPN-based client VPN: Useful for individual remote users who need to connect to the main network. OpenVPN is flexible and widely supported on various devices.
Notes:
- IPsec Site-to-Site is typically preferred for connecting offices or data centers.
- OpenVPN-based client VPN is a solid choice for individual remote access when you don’t want to expose your internal routing settings to end-user devices.
- WireGuard is growing in popularity, but always check your EdgeOS version and hardware compatibility before enabling it.
Below you’ll find practical, user-friendly steps for the two primary Edgemax VPN setups: IPsec Site-to-Site and an OpenVPN-style client VPN.
IPsec Site-to-Site VPN setup EdgeRouter UI and CLI
Site-to-site IPsec creates a trusted tunnel between two networks. Here’s how to set it up in a typical EdgeRouter environment. Adapt as needed for your firmware version and network specifics.
- Gather peer information
- Remote gateway IP the other site’s EdgeRouter or VPN gateway IP
- Remote network: the subnet on the other site you want to reach e.g., 10.10.20.0/24
- Local network: the subnet on your site e.g., 192.168.1.0/24
- Pre-shared key or set up certificates if you’re using cert-based IKE
- Access EdgeRouter
- Log in to the EdgeRouter web UI https://
- Navigate to the VPN section the exact path may vary by firmware, but it’s typically under VPN > IPsec or VPN > Site-to-Site
- Create the IPsec Site-to-Site tunnel UI approach
- Add a new Site-to-Site VPN panel
- Enter Remote Gateway: remote IP address
- Enter Local Network: your internal network e.g., 192.168.1.0/24
- Enter Remote Network: the remote network e.g., 10.10.20.0/24
- Authentication: PSK. set a strong pre-shared key
- IKE Phase 1 parameters:
- Encryption: AES-256
- Hash: SHA-256
- DH Group: 14 2048-bit is a common choice
- Key Exchange: IKEv2 preferred for reliability
- IPsec Phase 2 parameters:
- PFS: Enable with Group 14 or similar
- Local and remote subnets for the tunnel are defined above
- NAT-T: Enable if you’re behind NAT
- Save and apply
- CLI approach alternative or advanced
If you prefer CLI or your UI labels differ, you can configure with EdgeOS-style commands. Example adjust to your networks and secrets:
- set vpn ipsec site-to-site peer
authentication preshared-secret ‘ ‘ - set vpn ipsec site-to-site peer
ike-group - set vpn ipsec site-to-site peer
esp-group - set vpn ipsec site-to-site peer
tunnel 1 local-subnet 192.168.1.0/24 - set vpn ipsec site-to-site peer
tunnel 1 remote-subnet 10.10.20.0/24 - set vpn ipsec auto-status enable
- set vpn ipsec nat-networks allowed-ip-address 0.0.0.0/0
- commit. save
- Firewall rules and routing
- Create firewall rules to allow VPN traffic typically you want to permit IPsec traffic on UDP 500, UDP 4500, and IPsec ESP.
- Add a static route or adjust your routing table so traffic destined for the remote network goes through the VPN tunnel.
- Make sure you have a path for return traffic and avoid asymmetrical routing that can break the VPN.
- Testing and validation
- Use ping or traceroute from a host on Site A to a host on Site B to verify reachability.
- Check the IPsec status in the EdgeRouter UI or via CLI: look for “IPsec SA established” or similar indicators.
- Confirm that traffic is not being blocked by the firewall and that NAT isn’t altering the source addresses inappropriately.
- Common pitfalls and quick fixes
- Overlapping subnets: adjust either local or remote networks to avoid conflicts.
- PSK mismatch: re-enter the pre-shared key on both sides. a mismatch will prevent tunnel establishment.
- NAT issues with double- NAT: consider a direct public IP or proper NAT traversal settings.
- Mismatched IKE/ESP proposals: both sides should agree on encryption, hash, and DH groups.
Client VPN setup OpenVPN-style on EdgeRouter
Client VPNs let individual users connect securely to your central network. OpenVPN remains widely supported and relatively straightforward to configure on EdgeRouter devices.
- Decide on a server mode
- OpenVPN server for remote clients
- Ensure you have strong TLS/SSL settings and a proper certificate authority if you go with certificate-based auth.
- OpenVPN server configuration UI approach
- In the EdgeRouter UI, navigate to VPN > OpenVPN or OpenVPN server
- Enable the OpenVPN server
- Choose the server subnet for clients, for example 10.8.0.0/24
- Set the port 1194 is standard and protocol UDP is common for performance
- Configure TLS/SSL settings and authentication method
- Create user accounts or certificates for clients
- Apply the configuration
- Client configuration
- Export a client profile or provide the necessary files to clients
- Install an OpenVPN client on each device Windows, macOS, iOS, Android
- Import the profile, connect, and verify you can reach internal resources behind the EdgeRouter
-
CLI OpenVPN alternative
If you’re comfortable with the command line, EdgeOS supports OpenVPN server configurations via CLI too. You’ll typically define server mode, client certificates, route push options, and firewall rules to allow VPN traffic. How does edge vpn work -
Firewall and routing for OpenVPN clients
- Create firewall rules to allow VPN clients to access internal networks responsibly
- Route client VPN subnet e.g., 10.8.0.0/24 to internal networks you want reachable
- Ensure NAT is configured if needed so clients can reach the internet via the EdgeRouter’s WAN
- Security considerations
- Use strong TLS certificates and rotate them periodically
- Require user authentication for each VPN client
- Keep the OpenVPN software up to date and monitor firmware for EdgeRouter updates
- Troubleshooting tips
- If clients can connect but can’t reach internal hosts, double-check routing tables and firewall rules
- If the VPN drops, check idle timeout settings and keepalive options on both server and client sides
- Test using multiple clients and networks to identify where the issue lies client device vs server
Security best practices for Edgemax VPNs
- Use strong encryption and modern algorithms AES-256, SHA-256 and avoid older, weaker settings
- Prefer IKEv2 for IPsec if supported. it’s generally more stable and faster for mobile clients
- Enable Perfect Forward Secrecy PFS for IPsec Phase 2
- Use unique pre-shared keys or, preferably, certificate-based authentication for IPsec
- Lock down firewall rules to minimize exposure: only allow necessary traffic to and from VPN endpoints
- Monitor VPN logs and set up alerts for unusual login attempts or connection drops
- Keep EdgeRouter firmware updated to benefit from security fixes and improvements
- Consider segmenting VPN traffic from regular traffic with separate NAT and firewall policies
Performance and reliability tips
- Choose hardware with enough CPU and RAM to handle VPN load, especially if you have many remote clients
- For IPsec, enabling AES-NI if available on your device can significantly speed up encryption
- Use separate VLANs and subnets for VPN clients to simplify routing and security
- If you’re using dynamic WAN addresses, pair VPN with a reliable dynamic DNS service to keep peer connections stable
- Regularly audit and prune VPN users — remove access for departed employees to reduce risk
Real-world use cases
- Multi-site business with two or more branches sharing a central resource pool files, apps, printers via IPsec Site-to-Site
- Remote workers needing secure access to internal tools, with OpenVPN-based client VPN or IPsec client connections
- Small businesses wanting to keep a tight security posture without paying for enterprise-grade hardware but still benefiting from encrypted tunnels
Troubleshooting quick-start checklist
- Verify both ends’ VPN configuration IKE/ESP proposals, PSK or certificates, local/remote subnets
- Check firewall rules to ensure VPN traffic isn’t being blocked
- Confirm NAT settings aren’t altering VPN traffic in unexpected ways
- Validate the VPN tunnel status established vs. pending
- Test from multiple devices and networks to rule out client-specific issues
- Review log files for error codes or denial messages
- Confirm firmware versions are compatible across both sides of the tunnel
How to maintain and update your Edgemax VPN setup
- Schedule regular firmware updates for EdgeRouter devices
- Periodically rotate pre-shared keys or renew certificates
- Revisit and test firewall rules after updates or network changes
- Maintain a documented network diagram showing Site A and Site B subnets and VPN tunnels
- Keep backup configurations safely stored so you can recover quickly if a device fails
