Please clarify:

You live on 24/8 as an ATT broadband subscriber.  You try to communicate 
with another ATT broadband subscriber on 24/8.  Your outbound packets to 
said subscriber on 24/8 are dropped unless destination port is one of tcp 
ports 25, 110, 80, 443 or icmp.  The rest of your outbound packets to the 
internet as a whole are forwarded as usual.

Is that a reasonable re-wording of your original post?
