So the problem is when ive made an lobby in red alert 3 multiplayer an we set the whole match up, it just says that problem with connection progression 1-2 something and never starts, i tried to use dmz and portforward some procols from another thread but nothing worked, i used vpn too but that didnt work either. Im using windows 10 and have used compalibility settings aswell.
What can i do?
In the snipshot it says my Nat type wont negotiate, and i need to dmz or portforward but i dont know to what?
