Hello,
I installed and configured Wireguard fro OMV6 according to OMV wiki, and it works just fine using port 51820/UDP. Afterwards I configured the firewall for IPv4 through the GUI like this:
My active physical NIC: enp2s0 My wireguard NIC: wgnet1 . Servers local address: 192.168.0.100
Now I want to drop any other input ports so I add "input drop" to the end of this list and apply. After this my wireguard client cannot authenticate to the server.
I have no idea what I am doing wrong here. I would also prefer to use GUI for firewall settings so that later I can configure it easily
Any idea what I am missing here?
