Trouble hosting game server

I am trying to host a game server from home "Americas Army: proving grounds" is the game. I can launch the server but nobody can join it. I dmz'd the server and it was joinable. Turning off dmz makes it un-joinable again :(
Am i missing something?

Router port forwarding misconfiguration troubleshooting: If your network uses NAT behind a router, then you’ll have to forward some ports from the outside IP to the inside IP so that your server will authenticate, show up in game browsers, and allow connections from clients. ● 8777 (UDP) ● 8778 (UDP) ● 1200 (UDP and TCP) ● 4380 (UDP and TCP) ● 9987 (UDP) ● 27000-27030 (UDP and TCP) Firewall Misconfiguration Specific ports must be open in your firewall so that your server will authenticate, show up in game browsers, and allow connections from clients. ● 8777 (UDP) ● 8778 (UDP) ● 1200 (UDP and TCP) ● 4380 (UDP and TCP) ● 9987 (UDP) ● 27000-27030 (UDP and TCP)
