Time-Out Issues...

[DudemanGT]

Ok, Guys. i know you get this alot, but me and a couple buddies were lookin at settin up a LAN server here in Afghanistan. Ive been fiddling around a bit with the server to learn, and decided to let a couple guys on to see how it runs. HOWEVER, it times them out everytime, and always either right when they join or like 2 minutes after...

here's the error i keep getting every time:

Got any help? Thanks In Advance...

Oh, BTW, server is in offline mode, ip is assigned, ports forwarded and firewalls open, and running on 3G of memory on startup
