Remote Site Can't Resolve Domain Name
DNS names are never part of the TCP headers of any packet. Many sites do a reverse lookup of your translated IP address to determine your host's fully qualified domain name (note: the remote site is unaware you are using a "translated" IP address). If your translated IP address does not have a valid PTR record in your external DNS, it will not work.

Answer

This isn't a firewall issue, but rather an issue with your external DNS. You will need to contact whomever is in charge of your reverse DNS to resolve this issue.
