Have you logged into the Comcast device to see what options it offers for
firewalling and portforwarding itself? They may not all be the same, but the
one's I've seen do NAT as well as pass-through of the public addresses and have
some other options that may be all you need. A google search should turn up the
login and password you need for access if you don't already have it.
