me and a mate have been trying for a couple days to get a game of hoi2:dd/arm going but we're never able to get up and running. valkyrienet and connect via ip both say game host not found, and even when we hooked up to a hamachi server it said the same thing. we both run dsl through a router and have both set our hamachi port to tcp/udp 45000 and the proper ports forwarded. when i ping him over hamachi it works fine, however when he pings me it doesnt work. halp :<
 
Make sure you both have DMZ enabled for your router to your computers and if you have a modem and a router a DMZ or static nat from your modem to your router and then a DMZ to your computer also make sure all your firewalls are setup to allow the game to go through

and finally something that I only found out recently which was keeping me and my brother from playing multiplayer is disabling UPnP on your router and/or modem
