Strange networking issue possibly regarding Windows 10

[Zinx777]

I knew it''s something router related lol.
It looks like it less affects games that dont use adhocmatching but also games that use infrastructure mode in addition to adhocmatching.
Thats kinda a rare combination though.

Shame that the problem seems to be prevelant in a lot of games though and not so few...

This also seems to validate what you said : https://serverfault.com/questions/485150...158#485158

Isn't this all connected to how proadhoc cant use more then one device on a LAN over the internet/public ip?

As I understood from Linblow , the client socket source port js ignored over on that implementation.

So it wont matter if you checked or not.
