For now I had great problems with Thomson TG789vn router/modem. I can forward ports and ports works according to the test with FSPortTest, but sometimes I can't connect to FShost sessions because not all players can establish contact with me.
When I check with Wireshark many sessions use other ports than stated here. Port 10010, 52580, 58159, 14402 are in use. I try to open these ports in my TG789vn and ports indicate it is open, but I can't connect. Why are these ports in use?
When I use a VPN-tunnel all works fine.
There must be some special configuration in the router, but how to do that and what is that config called.
