What about this theory (although I don't know anything about the AOL stuff)
that the client connects to AOL. AOL sets up a tunnel with this client
and assigns 172.144.233.136 to it. Then due to the static DNS settings
on the client, a DNS query is made to your named on the firewall, instead
of using AOL's DNS server?
