Thanks @gg30340
I think I've narrowed down the problem. I have opened some ports for gaming, port 3659 udp
This also opens automatically if I enable upnp.
If I just port forward 3659 to 3659 it doesn't work as it should, although upnp believes this is what it should open.
When I use wireshark (packet analyzer) I notice packets being sent from server side on port 21010 udp to port 3659udp So I set the port forwarding up for this.
As soon as I start playing again the data is being sent via 21009 udp to 3659 udp. Any way I can resolve this?
