For those of you that have tried the "sticky" pages, and you still have a nat type strict, I have a minor suggestion for you which worked for me. First, make sure you have tried the suggestions from the sticky pages (DMZ, portforwarding, etc). I have a dlink-655 (revision B, 2.03 Firmware), a motorola surfboard sb5120, and my ISP is comcast. Here is the suggestion for you. If you have changed your router (I was previously using a linksys router), reset your MODEM to defaults. For some reason the linksys had changed some settings causing a "strict" nat type when I installed the dlink. For the surfboard, the IP is 192.168.100.1. Click on configuration, and click on "Reset all default." Also, make sure you are using the current firmware update for your router. This has worked for me when I finally realized certain settings were changed when I logged into my modem when DMZ and portforwarding failed to give me an open nat type. I hope this works for you. Good luck!

Could you explain this? I have some inside knowledge which may help find out whats actually going on but need more info.
"For some reason the linksys had changed some settings causing a "strict" nat type when I installed the dlink"
If you installed the Dlink, why was the Linksys still hooked up?

Yea, sorry. That might have been confusing.
I was upgrading from a linksys WRT54GL. The linksys was not on the network anymore (I have trashed it); however, something strange happened when I installed the dlink onto the network. I noticed that I didn't have any internet connection when directly connected to the modem...strange (I did have a connection through the router, but no connection directly connected to the modem.)
I then logged into my modem, and looked at the logs, and I noticed some strange bridging between the time when I had the linksys and dlink routers. I then reset the modem to defaults, and everything worked from then on.
I hope this helps.

Possible this is a corner case issue for your setup however my experience for most any Motorola SB series modem is that these modems accept for a couple that have built in routers, act normally as modems and don't have any bridging options and shouldn't pose a problem or cause Strict NAT messages. If the sticky's are used correctly for PSN or XBL, they will and do correct NAT issues and sets them up for OPEN every time. I and others have some form of SB series modem and I currently run the DIR-655 router and all NAT is OPEN using the sticky information with out having to use DMZ at any time.
Maybe someone can review your routers settings with you using Teamviewer. (http://www.teamviewer.com/)
