I'm testing a network library called enet. When I make connections on port 1720 using 192.168. IPs, my laptop (client) connects to my PC (host) no problem. When I connect my PC with PPPOE and use the new IP (76.86...) then I never get anything.
I've tried forwarding port 1720 to the PC,forwarding it to the laptop, using DMZ, nothing at all works. What could I be doing wrong?
