For 2 months I've been trying sfml, enet and other various networking libraries. But none of the mentioned networking programming tools(enet, SFML...) would work for me. I've tried shutting my firewall with open ports for both UDP and TCP connection, but nothing worked. I also tried several computers when trying this but with no success.
I've been running PRECOMPILED samples that came with SDKs so they should be robust and stable.
So Is there any software that can show what is blocking my pc from connecting to other PCs?
PS. I have no router. When using local host all programs work perfectly. Games like CSS, ArmA 2, Fallen Earth can connect to their servers...
Well any suggestions would be appreciated.
