I have the exact same problem. AT&T converted our area from DSL to DSLAM and none of the attempts to set up the router to port forward ha worked. I can't seem to get any answers from Slingbox or AT&T. AT*T has me hooked up through a Motorola NVG510 router/modem. Everything worked fine when I used my own router (Netgear) which had the port forwarded on port 5000. Now I try to set it up through the Morola/AT&T router/modem to no avail. Someone needs to come up with a solution.
