We've seen some interesting connectivity issues for ATT users recently. The most recent was some sort of ALG proxy on anything destined to udp/4569. This appears to intercept registration traffic and then selectively forward it on. I'm at a loss as to why this is happening. Last weekend ATT stopped allowing one of the subnets for the stats server in their routing table too. That was a bit easier to troubleshoot and easier to reach someone on their backbone with clue. The stats server isn't a critical part of the network either. If you're having any issues, please try registration on port 4566. I'll stress again, this really isn't an AllStar issue, it's a crappy ISP breaking the internet issue. There's not much the admin team can do if your ISP isn't going to route packets properly :( -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net
