Connecting Fritzbox to OPNSense using Wireguard

[serversonic]

I can see some activity in the forum regarding this in German but it's a lot to read through Google Translate.

My home broadband has a Fritzbox that has been updated to support Wireguard, and I have a remote OPNSense VM with Wireguard installed. The Fritzbox either creates a Wireguard configuration file to install on a remote device, which is mostly intended for mobile devices, or requires a Wireguard configuration file generated by the remote device.

I have tried manually creating a configuration file from an OPNSense connection to import into the Fritzbox but can't get this to work. I have also tried in the other direction and have had no success that way either. On the OPNSense VM I can see that outbound connection attempts to negotiate but fail. I don't have any meaningful logging on either side to diagnose.

So I think in this order:
- Has anyone achieved this kind of connection?
- Can logging be enabled for Wireguard, and how?
- Is it possible to export a Wireguard confiig from OPNSense at all
- Would it be possible to add this to the Wireguard plugin?

Thanks
Simon

This resource goes explaining what needs to be done https://homenetworkguy.com/how-to/configure-wireguard-opnsense/. I imagine you can use it to figure out what to do on each peer.

Thanks, I found that, it was pretty much what I was following, but the Fritzbox is the hard bit as it doesn't give away a lot in terms of debugging information.

Hallo zusammen,
ich stehe vor dem gleichen Problem.

Hat jemand schon eine Wireguard Verbindung zwischen OPNsense und Fritzbox hin bekommen?

Maybe you should open an new thread in german sub forum or search for existing threads regarding this issue (mentioned in post #1).
