I have a router connected to a hub that connects two computers. I have some own-developed programs that connects via socket connection from one computer to the other. But after doing a factory reset of the router, these programs are unable to make a connection. I can still ping the computer though.
Not sure where to start.. Would I need to set up some address/port forwarding or something in the router in order for this to work?
Visual Studio gives SocketException:
No connection could be made because the target machine actively refused it 192.168.1.xxx:xxxx
