Is the wireguard interface up?

5

Yes up and I use wireguard effectively wo issues.

Well, I’m not sure now but I think samba cannot listen on L3 (tun) interface but only on L2 (physical ethernet or TAP) interfaces. Thus you cannot make samba listen on wg interface.

I might be wrong.

It seems samba can listen on tun interfaces as well.
