AT&T@Home Blocks Port 80

In response to the Code Red worm(s), AT&T broadband/Excite@home is blocking port 80. Port 80 is the port that webservers run on and thus also the one that Code Red has been using to spread. Verizon is apparently doing the same for their DSL customers. As annoying as it may be, I think this is the only way to stop it since far too many cable/DSL folks running IIS either don't know or don't care to patch their servers. I thought that most broadband EULAs specifically forbid running servers anyway. Thanks Slashdot.

J.t.Qbe comments: I wonder when the filtering is supposed to begin--from the blinking of my cable modem's data light, it hasn't begun yet! I was reading my AT&T Subscriber Agreement last night and didn't find any "no server" clause. I thought I'd read somewhere that home users weren't allowed to run servers (maybe I saw it on the @Home website), but according to the page you linked and the SA, it must be allowed, at least for web servers.
