This used to work before i changed to U-Verse so here is my current setup. I have a 2nd router behind the U-verse router. The U-verse router is setup to all everything to pass-thru the 2nd router. All my network pieces are connected to the 2nd router. 1st sling box works fine on port 5002 and address ending in .254. 2nd Slingbox is on port 5001 and IP .253. Port forwarding is open for ports 5001 & 5002. everything is setup the same for both so i can't figure this out. both slings are also behind switches. i can see sling #2 locally but not over the internet...help please.
