general 'I can't get it to work' thread yet again
I've done the port forwarding TCP and UDP to 7845 for ZSNES, translating to 7845. I use a BT Home Hub v5. I use ZSNES 1.36 because it was considered more stable than 1.4xx for netplay, I heard, and am using it on both OS X 'El Capitan' (10.11) and Windows 10 Home.
I got it to work over a local connection between the OS X and Windows computers on UDP, but can't seem to connect to an actual Internet connection, only a local network area, so I've definitely port-forwarded correctly.
Windows Firewall is turned off and the Mac doesn't have an Anti-Virus installed. I intend to use the Windows machine for ZSNES netplay.
Can somebody try to help? I suspect I've missed something out, or I'm being an idiot, but blarg.
