Let me start off saying I haven't really addressed this with Comcast yet.
Here's what's happening, I'm a radio engineer, and a few of my clients use Comcast as a STL (Studio to Transmitter Link). Doing this several times, most recent being last night, Comcast has decided to block the port the Audio is streaming on.
In the case last night it was Port 9001, initial symptom audio broken like packet loss. After an initial check I rebooted the modem, and then absolutely nothing. The STL devices would no longer connect at all. Luckily the web servers are on a different port and I was able to shift to port 9005 and everything came right back up working nicely.
I'm just curious as to why they would target a port that has been streaming since the circuit was installed.
Is their something about port 9001 that would make it a target for blocking?
In an earlier situation port 9001 was blocked, moved to 9002 it worked for a couple weeks before being blocked, I was up to 9005 prior to shifting off Comcast due to their inability to correct a upstream packet loss problem at the studio site.
