Connection Problems Randomness!

[Promythyus]

Hey,

Me & My Friend are Having some problems playing games in the DoW Lobby.
Sometimes, We Connect and have a good game, this is about 1 in 15 times (we tested 15 times :p), sometimes, we will have "Could not find host", we got this the rest of the time. Also, Sometimes when we finally do get a game working, I get a Sync-Error Detected, but i have no modified content in my folders. He & I can Play with Other People Perfectly (expect for team-betraying n00bz :banghead:).

My Network is Like this: Net -> Router -> Linux Firewall -> Smartswitch -> My Computer. I have opened the relevant ports on my computers firewall, the linux firewall & the Router.

My Friends Network is like this: Net -> University -> Router -> Wireless Hub ~> Laptop. He has Disabled all firewalls on the computer, expect the university one (because he can't).

These are our Net Test Thingamabobs:
My Test:

Sending udp packet from 6112 to 6112
Received from /66.134.89.225:6112 to 6112 "udp pass"

Any Help Would be awesome!

That result shows that most of your ports are firewalled on both PCs. Your friends one if its to a University server is probably unfixable. You need to port forward those ports to your PCs given address

I've been looking around abit, on the net & on computer. so far i have forwarded the ports to the Linux Firewall, but now I need to know how to forward ports from it to my computer. It Runs Fedora Core 6 with Custom IPTables, anyone know how?
