I apologize for the caps on title, but I wanted to make sure this was seperated from other warcraft 3 posts, and that future searches like mine will turn this up.

The Problem:

I cannot host warcraft 3 maps. The original problem to which im addressing is the issu that I follow steps at portforward.com but the results are different than they have been in the past. Likely because of the different router. My second problem opens when I decide to take the router out of the picture and go with a direct connection from modem to PC. This unfortunately, and to my surprise - doesn't work.

Stumbling onto this site through google, where someone with a linksys router has an issue, I decided to post.

My router: Linksys Dual-Band Wireless-N Gigabit Router (please explain dual band vs regular router too if you can.)
Model #: WRT320N

My moden: Provided by CoxCable in northern Florida the Identification is as follows...
Model #TM602G
Company: ARRIS


What I have tried so far:

I made static ip with last digits being only 101-110
Logged into my router and opened ports 6112-6119 for war3
Installed the port checker only to find ports closed. However, ports are reported opened when directly connected to modem. Otherwise they are closed.
In all situations I have had my firewalls both off and on. All exceptions made. Using McAfee for protection


Any quick reply would be appreciated, thanks.
