• Low cost with decent throughput for IPSec VPN tasks
• EdgeOS’s clean CLI and GUI for quick config
• Solid documentation and a supportive community
• Small footprint, easy to mount, with integrated 802.11ac depending on model variations

VPN fundamentals you should know

• IPSec: A suite of protocols to secure IP traffic. You’ll typically configure IKE IKEv1 or IKEv2 for key exchange and IPsec for the actual data encryption.
• Site-to-site VPN: Bridges two networks so devices on both sides can talk as if they’re on the same LAN.
• Remote access VPN: Lets individual users or devices connect to your network from outside, usually via a VPN client.
• Encryption and authentication: Common options include AES-256 for encryption and SHA-256 or SHA-1 for integrity and authentication SHA-256 is preferred.
• NAT traversal NAT-T: Important when VPN endpoints sit behind NAT devices.

IPsec Site-to-Site VPN on EdgeOS: step-by-step guide
This section assumes you want to connect two sites: Site A Edgerouter X and Site B remote gateway. You’ll set up a VPN tunnel, exchange keys, and ensure traffic routing between subnets.

prerequisites

• Two EdgeOS devices or one EdgeOS device and a compatible gateway
• Public IP addresses for both sites or a static/dynamic DNS setup
• Subnet details for each site e.g., Site A: 192.168.10.0/24, Site B: 192.168.20.0/24
• Basic firewall zones created trust, untrust

1. Plan the topology and phase 1/phase 2 parameters

• Phase 1: IKE version IKEv2 recommended, pre-shared key PSK or certificates, encryption AES-256, integrity SHA-256, DH group 14/OF DH-14 is common
• Phase 2: IPSec SA ESP with AES-256, PFS group 14 or 15 is common, lifetimes 8 hours to 1 day depending on policy
• Traffic selectors: Local LAN to Remote LAN subnets
• NAT-T: Enabled if either site sits behind NAT

2. EdgeOS configuration basics CLI or GUI

• Create firewall zones: lan, wan, and a VPN zone if you want to segregate VPN traffic
• Define static routes for remote site subnets if needed
• Ensure NTP is functioning to keep keys in sync

3. Example CLI configuration illustrative

• This is a simplified outline; replace with your actual subnets and public IPs.
• Interface and IP setup:
  • set interfaces ethernet eth0 description ‘WAN’
  • set interfaces ethernet eth1 description ‘LAN’
  • set vpn ipsec site-to-site peer pre-shared-secret ‘‘
  • set vpn ipsec site-to-site peer ike-group
  • set vpn ipsec site-to-site peer tunnel 1 local-ip remote-ip
• IKE and IPsec parameters:
  • set vpn ipsec ike-group lifetime 28800
  • set vpn ipsec ike-group proposal 0 encryption aes256
  • set vpn ipsec ike-group proposal 0 hash sha256
  • set vpn ipsec ike-group mode main
  • set vpn ipsec ipsec-group proposal 0 encryption aes256
  • set vpn ipsec ipsec-group proposal 0 hash sha256
  • set vpn ipsec ipsec-group pfs enable
  • set vpn ipsec site-to-site peer tunnel 1 local addr remote addr tunnel 1 esp-group

4. Firewall and routing

• Allow VPN traffic to pass: set firewall name VPN-In default-action drop; set firewall name VPN-In rule 10 action accept; set source address VPN_NET; set destination address LOCAL_NET
• Add static route: set protocols static route next-hop blackhole no
• On Site B, mirror the same with reversed local/remote subnets

5. Verify and test

• Check phase 1 IKE and phase 2 IPsec statuses
• Ping across subnets Site A to Site B
• Check peer status, tunnel status, and logs for errors
• Validate MTU and fragmentation as necessary

6. Troubleshooting common issues

• IKE phase fails: verify time drift, PSK mismatches, and correct remote peer IP
• IPsec SA not established: ensure matching proposals and lifetimes
• Traffic not routing: confirm firewall rules permit VPN traffic and static routes exist
• NAT-Traversal issues: ensure NAT-T is enabled if behind NAT

Remote access VPN on EdgeOS: step-by-step guide
Remote access VPN lets individual users connect to your network securely. Two common approaches are L2TP over IPsec and OpenVPN style configurations. EdgeOS has built-in support and makes setup relatively straightforward.

prerequisites

• Public IP or DNS for the EdgeRouter X
• Client machines with a VPN client compatible with the chosen protocol L2TP/IPsec, OpenVPN, or WireGuard if supported by the Edge firmware
• A plan for user authentication PSK for simpler setups or certificates for stronger security

1. Choose your remote access VPN protocol

• L2TP over IPsec: simpler, widely supported, decent security with strong PSK or certificate-based authentication
• OpenVPN: highly compatible, great control, but may require additional packages or compatibility steps on EdgeOS
• WireGuard: modern, high performance, but may require newer EdgeOS builds or community packages

2. L2TP over IPsec setup typical approach

• Create a VPN user and assign a shared secret for IPsec
• Create a tunnel interface on EdgeOS
• Configure IP pool for VPN clients e.g., 10.8.0.0/24
• Add firewall rules to allow VPN client traffic
• Ensure the EdgeRouter X forwards VPN traffic to the LAN and supports NAT if needed

3. OpenVPN setup if supported

• Install and enable the OpenVPN server on EdgeOS
• Generate server and client certificates or use a pre-shared key approach
• Configure client profiles .ovpn for distribution
• Set up firewall rules to permit OpenVPN traffic and route client traffic to LAN

4. WireGuard setup if supported

• Create a WireGuard interface and set private keys
• Add peer configurations for each client with allowed IPs
• Enable NAT and proper firewall rules
• Distribute client configuration including public keys and endpoints

5. User management and security considerations

• Enforce strong passwords or use certificate-based auth
• Enable MFA if possible or require regular password changes
• Limit VPN users to only necessary subnets
• Monitor VPN login events and set up alerts for unusual activity

6. Testing remote access

• Connect from a client outside your network
• Verify you can reach internal resources servers, printers, NAS through the VPN
• Check latency and stability, adjust MTU if needed

Performance and security considerations

• Throughput: EdgeRouter X can handle several hundred Mbps of VPN traffic under IPSec depending on CPU, encryption, and tunnel count. Realistic expectations: 100-200 Mbps IPSec with AES-256 on a typical consumer-grade line.
• CPU load: VPN processing is CPU-intensive; disable unnecessary services to optimize performance.
• Encryption level: AES-256 with SHA-256 offers strong security; consider AES-128 if you need more headroom for throughput and your threat model permits.
• Regular updates: Keep EdgeOS firmware up to date to patch vulnerabilities and improve performance.
• Logging and monitoring: Use system logs and VPN status pages to monitor performance and security incidents.

Template 3: Remote Access VPN OpenVPN style, if EdgeOS supports

• Generate server and client certificates
• Configure server with push routes to internal networks
• Provide client profile to users
• Secure with TLS and appropriate cipher settings

Advanced tips: routing, NAT, and firewall rules

• Split-tunnel vs. full-tunnel
  • Split-tunnel routes only specific subnets through VPN; full-tunnel sends all traffic through VPN
• NAT rules
  • If you want VPN clients to access the internet via the VPN, enable appropriate NAT on the EdgeRouter
• Firewall zoning
  • Create a dedicated VPN zone to isolate VPN clients from the main LAN if you want stronger security
• DNS considerations
  • Route VPN clients to internal DNS servers for name resolution, or use public DNS if internal resources aren’t name-resolved internally

Overview of Edgerouter x vpn configuration

Edgerouter X runs EdgeOS, which provides a robust, Linux-based environment for configuring IPsec VPNs. The core idea is to create a tunnel between two networks site-to-site or between a client and a network remote access using IPsec with strong encryption and authentication. In practice, you’ll:

• Define a secure authentication method Pre-Shared Key or X.509 certificates
• Create an IKE IKEv1/IKEv2 group with strong ciphers
• Create an ESP IPsec policy for data integrity and confidentiality
• Configure a VPN peer with local/remote endpoints and subnets
• Open the right firewall ports and set NAT rules to ensure traffic flows correctly
• Test the connection and troubleshoot common issues

Pro tips:

• Use AES-256 for encryption and SHA-256 for integrity.
• Choose a DH group like 14 that balances security and performance.
• If you’re on a home ISP, consider using a dynamic DNS service so the remote site can reach you even if your WAN IP changes.
• Always back up your current configuration before making changes.

Through this guide you’ll see concrete commands you can adapt to your local IP addresses and network ranges. The goal is to give you a solid working VPN in a way that’s reproducible and easy to maintain.

Choosing between site-to-site and remote access

• Site-to-site VPN: Great for permanently linking two networks e.g., home/home office and branch office. It’s usually a pair of endpoints you configure once and then traffic between subnets stays routed over the tunnel.
• Remote access VPN Road Warrior: Best for individual devices or travelers who need to connect securely to a single network. This is typically used by you or employees who need to connect from remote locations.

What to prepare:

• Remote endpoint details: outside IP address or hostname, subnet at the remote site
• Local endpoint details: your EdgeRouter X WAN IP, local subnets
• Authentication method: pre-shared key PSK or certificates
• IP addressing: avoid overlapping subnets. plan tunnel-local and tunnel-remote subnets

Performance considerations and security best practices

• Encryption and speed: AES-256 is secure, but it can impact throughput on cheaper hardware. Expect some performance drop when encryption is enabled. If you have a lot of traffic or larger remote sites, consider a hardware upgrade or tuning the ESP lifetimes and PFS settings to balance speed and security.
• Keep firmware current: EdgeOS updates frequently include security fixes and VPN stability improvements. Regularly check for updates from Ubiquiti.
• Use strong authentication: Prefer certificate-based authentication if possible. otherwise, use a robust PSK long, random, unique per site.
• Subnet planning: Avoid overlapping subnets between two sites to prevent routing conflicts and traffic leaks.
• Firewall hardening: Create a dedicated VPN firewall rule set that only allows necessary traffic to pass over the VPN tunnel and restrict management access from the WAN.
• Monitoring: Enable logging for VPN events and inspect the logs periodically to catch authentication failures or tunnel drops early.
• Redundancy: If uptime is critical, consider a secondary WAN path and a backup VPN tunnel to reduce single points of failure.

Automation and maintenance tips

• Scripting common changes: If you manage multiple sites, script common VPN settings and use templates to push configuration updates across devices.
• Configuration backups: Regularly export and store backup configurations so you can restore quickly.
• Change management: Document any changes with dates and reasons. Version control helps you track what changed and when.
• Centralized monitoring: Use syslog or a network monitoring tool to alert you when VPN tunnels come up or down.
• Regular testing: Schedule periodic end-to-end tests that verify connectivity across the VPN, not just tunnel status.

Performance metrics you can rely on

• Real-world VPN throughput: Expect a practical reduction of 10% to 40% depending on encryption, tunnel mode site-to-site vs remote access, and CPU load.
• Latency impact: VPN tunnels add a small amount of latency. on a home connection with a couple of hundred Mbps, you might see 1–8 ms extra latency per hop.
• CPU usage: EdgeRouter X uses a single CPU. higher encryption strength and larger traffic can push CPU usage up. Plan for peak load rather than average load.

Common pitfalls and quick fixes

• Subnet conflicts: Revisit your tunnel-local and tunnel-remote subnets if you see unreachable hosts on the other side.
• Mismatched PSK: Copy-paste PSK carefully. even a single character mismatch stops the tunnel from forming.
• Firewall misconfiguration: Ensure that IPsec traffic UDP 500/4500 and ESP is allowed between peers.
• Dynamic IP changes: If the remote endpoint’s IP can change, add a dynamic DNS entry and update the VPN peer to use the hostname, or use a dynamic VPN solution that handles IP updates automatically.
• Certificate expiry if used: If you go certificate-based, monitor expiry dates and have a renewal process in place.
