Hello - I troubleshot this problem extensively with a packet capture spanning the vlan between the 2wire router and my DD-Wrt router. (Used to run it on a wrt54G, and then upgraded to a buffalo router running dd-wrt, but problem still continued.) I saw the drops coming from the ATT 2-wire router and had them replace it. GREAT!! The problem no-longer occurred! A few days later I realized I was no longer in DMZ+ mode, so switched things back around. What do you know, the problem started re-occurring on me! The issues are no packet loss, because TCP would retry. The issue is with hung connection states. I am not 110% sure if it is on the 2wire side, or the way dd-wrt interprets the DMZ+ mode configuration. (Although my previous cable modem connection, with the public IP on the dd-wrt box NEVER had an issue) I have been doing double port forwarding for the past 1.5 years now. I do however plan to hook up a different firewall to the ATT box and turn on DMZ+ mode. We will see if the issues re-occur.
