Looped interfaces? Odd behaviour

[Gralq]

Hi!

I'm taking my first stab at opnsense and I have some odd behaviour.

I have my router (TLSense J6412 from teklager.se) up and running. It's connected to my gaming pc, a switch and Unify AP.

Everything is functioning as it should as long as my gaming pc is connected. But when it is disconnected the routing seems to shut down. I have still have links (the lights flash atleast) on all ports, but wireless goes down and I can't connect to anything within my network.

The only additional config done to opnsense other than the default one is that I've set up a VPN server.

Does anyone have an idea of what could have happened? Or how I can try to find the error?
