Hello all, I am new here and I hope some one might help me. I have an issue which may be router/firewall related and I have next to no knowledge on that or networking systems. Me and a friend are trying to play a game online together and I try to start a stand-alone server through my own machine. On my friend's end gets messages saying I am blocking with possibility of a router or firewall or such. I have tried disabling my firewall but that had not worked. Any help would be appreciated!
