I'm trying to share an IP address between two IP addresses using static PAT, which works fine. The problem comes with the IP address each machine takes when they send outbound traffic (i.e., e-mail). Both machines use the public NAT address for the firewall, but for reverse DNS checks to work properly, I need to resolve them back to their public IP address. There has to be a way around this?
