Comcast changed their DNS servers to no longer respond to unregistered
IP addresses.  Your system isn't set up for proper reverse DNS
in-house.

See numerous threads the last few days on ftp-proxy, ssh, telnet.  All
the same problem.  You aren't the only one.  

hmmm...  I wonder if this might be how they are tracking people using
more than one computer inside their network?
