Hi,
I used to use an external Wireguard connection to reach my companies network from my windows 11 host at home.
This does not work any longer after I updated OPNsense to 24.1.
The Wireguard protocol says:
Handshake to peer 1 (....) dit not complete after 5 seconds, retrying...
As far as I know, the Wireguard client uses UPD to communicate with the server.
I created a firewall rule in OPNsense to allow "any to any" with IP4 and TCP+UDP (just for testing).
The internal Windows firewall is deactivated.
Other Tools like Syncthing work fine. Syncthing also uses UDP on an specific port.
The OPNsense log-files does not contain any lines with the port I used for this Wireguard connection.
Does Anybody have an idea what's the problem could be?
It's getting even stranger.
When I use Wifi, everything works.
Using an normal LAN connection does not work.
What could this cause?
Well, the current version is 24.7.x. I'd start there.
Yes, Sorry. I User 24.7.
