Moving from OpenVPN to Wireguard and Wireguard isn't working? What I learned....

JustAnotherUser

I moved my setup from OpenVPN to Wireguard and no matter what, WG just wasn't working.

I HAD TO DELETE the entire OVPN setup (not just disable it) and after I did that, WG worked perfectly with no changes.

If you have ANY OVPN stuff on your pfSense box, delete it if you plan on using WG.

@JustAnotherUser I have WG and OpenVPN tunnels on at least 6 pfSense boxes. All work perfectly.

Like Jarhead.. I too have OpenVPN running and WG on my primary box.. What I believe you mean is that you have to delete the OpenVPN instances associated with the same link however I myself only disabled my OpenVPN instances as I moved them over to Wireguard and had no issues..

I will eventually move all mine over and will pay attention to the process a little closer in case I have issues.

@JustAnotherUser
did you save your config before trying to add the wireguard VPN? If so load the old config and reboot your system to get back to a known working router with OpenVPN.

Try again next week.

I run both wireguard and openvpn servers and clients simultaneously.
