Frequently Asked Questions

Table of Contents

How do I choose between WireGuard and OpenVPN for OPNsense?

WireGuard offers faster speeds and simpler configuration, making it a great default choice. OpenVPN provides broader compatibility and robustness in mixed environments. Your best bet is to start with WireGuard and fall back to OpenVPN if you encounter device or provider-specific limitations.

Can I run multiple VPNs on a single OPNsense box?

Yes, you can run multiple VPN tunnels or failover VPNs, but you’ll want to segment them with distinct interfaces and firewall rules to avoid traffic conflicts and ensure predictable routing.

Is VPN on OPNsense safe for gaming?

Yes, with proper configuration and a near-server, you can achieve low latency. WireGuard often provides better latency than OpenVPN, but results vary by location and server load. Nordvpn keeps timing out heres how to get your connection back on track

How do I test VPN performance from my network?

Use speed tests to benchmark upload/download, latency to the VPN server, and traceroutes to identify bottlenecks. Compare multiple VPN servers to balance speed and reliability.

Should I use a kill switch?

Definitely. A kill switch ensures that if the VPN disconnects, traffic doesn’t leak to the non-VPN interface.

How do I avoid DNS leaks?

Point DNS requests to a trusted resolver that is not controlled by the VPN provider, and ensure DNS requests are forced through the VPN tunnel.

Can I run VPN on a Raspberry Pi with OPNsense?

OPNsense is designed for x86 hardware, but you can run VPN clients on compatible devices in your network. If you’re using OPNsense as your firewall, the VPN tunnel would reside on the OPNsense box.

Do VPNs work with split tunneling on OPNsense?

Yes. Split tunneling lets you route only specific traffic through the VPN, preserving bandwidth for non-essential tasks. This is useful for streaming or local network access while keeping other traffic private.

How often should I update my VPN configuration?

Update configurations whenever your VPN provider changes endpoints, certificates, or security requirements. Regularly update OPNsense and plugin versions.

What about logging and privacy?

Check your provider’s logging policy and consider enabling no-logs configurations where possible. Use privacy-conscious providers and minimize data exposure.
