I am able to see the full listing in the lobby as well as get pings for each server.  I can also check friends and rankings through community menus.  I have timed out on every server that is showing 7777 for its port.  When I failed to connect through the lobby I attempted to connect directly through the console but that too failed.  I have been able to connect immediately and play with no trouble, aside from lag, on a Warfare Server hosted on 8777. I have been able to connect to a TDM server hosted on 7331 and a warfare server on 2222.  I have attempted to connect to a dozen or so servers that hosted on port 7777 and they all time out.  I know the issue is nothing with this server but as I have received no response from the official epic forum and this was the server I most played on, I decided to post here and hope for someone with greater knowledge of networking to point me in the right direction.  Since my original post I have also attempted connecting a USB network adapter to rule out an issue with the integrated nforce adapter. This yielded no positive results.
