Technically, you don't even have to use port forwarding, or opening ports when using hamachi. Just have people join your network, and make sure everyone has windows firewall disabled. It has worked for me in the past with UT2004... *shrug*

I am definately up for some more Quake wars.  Now that the objectives are known it should make the game more fun.

you might need to port forward for hamachi.  In the settings you can set it to use a specific port to connect and then just port forward that port.  That is what i do and it works like a charm.

Well, I have done this before... I've used Hamachi constantly(refer to sig, although I'm offline atm...bioshock and all) for a couple years now. If you want, shoot me a PM, I'll share my hamachi network info for you to test it out. I was playing UT2004 as well as ventrilo over my hamachi network a week before the 150, so I know it works.
