Reverse lookup fails for hosts behind firewalls and hosts with synamically assigned IPs.
Reverse lookup can work perfectly well behind a firewall. They are different things, not related. Reverse lookup depends on a name server only. I have a system running behind a firewall for years and reverse lookups work without any trouble.
