That's correct,  they also block a handful of other ports as well.

One way to see if the rule worked, is to run nmap from the outside of your
host. (neighbor, work, school, etc..)  don't portscan adelphia's servers though
as I think it's against their terms of service (though they can scan you
anytime...  nice rules eh? )
