How to install and configure VPNs on OPNsense

Here’s a practical, step-by-step guide you can apply to common VPN types. The workflow is similar across providers, but you’ll rely on different VPN plugins and configuration files.

Introduction to the platform:

Ensure your OPNsense is updated to the latest stable release.
Back up your configuration before making changes.
Consider enabling a separate VPN VLAN or DMZ for VPN endpoints to keep traffic segmented.

A. WireGuard on OPNsense recommended for speed

Install the WireGuard package:

Navigate to System > Firmware > Plugins and install os-wireguard or the WireGuard package available for OPNsense.
After installation, go to VPN > WireGuard and create a new instance.

Create peers and keys:

Generate private/public keys for server and client.
Add a peer for each remote device or site you want to connect.

Configure the server:

Define the Interface e.g., wg0, listen port default 51820, and allowed IPs 0.0.0.0/0 for full-tunnel or specific subnets for split-tunnel.
Add a peer: set public key, allowed IPs for the peer, and keepalive settings.

Firewall rules:

Create firewall rules to permit WireGuard traffic on the chosen port.
Route traffic as needed e.g., through the VPN tunnel or only to specific subnets.

Client side:

Export client configuration or import the generated config on clients supporting WireGuard.
Test connectivity and latency.

Tips:

WireGuard is usually the fastest option on modern hardware, but ensure your hardware has enough CPU power to handle multiple peers if needed.
Keep keys secure and rotate regularly.

B. OpenVPN on OPNsense

Install OpenVPN client and server components if needed:

Go to System > Firmware > Plugins and install OpenVPN if not already present.

Server configuration:

Create a new OpenVPN server instance, choose UDP as the protocol for better speed in most environments, and pick a server IP range e.g., 10.8.0.0/24.
Generate or import server certificates and keys.

Client configuration:

Create client export or provide client configuration files to remote users or sites.
Deploy the client configuration to devices that will connect to the VPN.

Firewall and routing:

Allow OpenVPN traffic on the server’s port.
Add appropriate firewall rules to allow VPN traffic and route traffic to the VPN interface.

Performance tips:

Use compression cautiously; in some cases, it can introduce security risks.
Tune MTU and TLS-auth settings for stability and security.

C. IPsec strongSwan on OPNsense

Install and enable IPsec:

Go to VPN > IPsec and add a new tunnel Site-to-Site or Road Warrior, depending on needs.

Phase 1 and Phase 2:

Set IKE version IKEv2 is preferred for modern setups.
Choose encryption and hashing algorithms aligned with your security goals and hardware capabilities.

Firewall rules and networking:

Create rules that permit IPsec traffic and route through the VPN interface.
Confirm NAT traversal settings if you’re connecting behind NAT.

Testing:

Use ping and traceroute to verify tunnel status and path stability.

Performance and security considerations

Hardware matters: A modern router with sufficient CPU cores and RAM will dramatically improve VPN performance, especially for OpenVPN. WireGuard tends to outperform OpenVPN on the same hardware.
Encryption profiles: Align your cipher and hash choices with security needs. For example, ChaCha20-Poly1305 is efficient on WireGuard, while OpenVPN may use AES-256-GCM depending on your setup.
Split tunneling vs full tunneling: Decide whether only specific subnets should route through the VPN or all traffic. Split tunneling can dramatically improve performance for non-critical traffic.
DNS leakage: Ensure DNS requests go through the VPN or use a DNS service you trust to prevent leaks.
Kill switch: Use a robust kill switch in OPNsense or on client devices to prevent traffic leaks if the VPN drops.
Logging and privacy: Understand your VPN’s logging policy. Even a VPN with a strong privacy stance can log metadata. Choose providers with clear, privacy-respecting policies.
Regular updates: Keep OPNsense, VPN plugins, and firewall rules up to date to minimize vulnerabilities.

Scenario checklist:

Define your primary use case: remote access, site-to-site, or both
Map out subnets and required access rules
Decide split tunneling strategy to optimize performance
Plan for backup VPN paths in case primary VPN goes down

Common mistakes and how to avoid them

Skipping backups: Always have a backup VPN path in case the primary tunnel fails.
Forgetting DNS protection: Ensure DNS queries don’t leak outside the tunnel.
Overly broad firewall rules: Start with minimal rules and tighten as you confirm traffic patterns.
Not testing on real devices: Test VPN connectivity on the devices you’ll actually use laptops, phones, IoT devices to avoid surprises.
Inadequate key management: Rotate keys and use strong, unique keys per peer.
