Why does this Java network code work in my LAN, but not cross-campus?
Posted on 2015-02-19
My java RTS game server works well with my client machine with 3 Java clients on my PC next to my Mac server, 1 foot away, with TCP messaging.
But, when I take my client class to my dad's office at the university, 4 miles away, the same code won't even make the initial TCP HELO message connection.
We initially had firewall issues, but the admin told us how to open the firewall.
What else could complicate initial TCP connections? There is no UDP, yet.
I currently run all the clients from the main() in my client class. It works fine at home.
But, the TCP isn't isn't making any long-distance connections.
