1/17/2008: Setting your linksys router for Halo 3
If you're experiencing lags and disconnections, chances are your router is not optimized for Halo 3, if you have a linksys router, try the following...
To start, browse to your router's management webpage, at http://192.168.1.1/

For starter, disable uPnP, this causes alot of lag and disconnection problems.
The next thing to do is make your Xbox 360 your DMZ machine. DMZ basically means all external ports are pointing to the Xbox. First if you do not know your Xbox IP address, use these steps to find the IP address. Make note of the last number (in this case, it's 100)

From there, click on Application and Gaming, Enable DMZ and put in the address noted in previous step. That's it.
Other brand routers should have these settings, they maybe in different menus.
