I have to configure two public IP's to a SMTP and a webserver. Port address translation is configured to ports, 80, 443, 110, etc. This extra SMTP server is registred with its own dns name webmail.company.com and the webserver is registred with another public IP address for its dns with company.com. Do I need to configure two interfaces to accomplish this? I know this is possible if you configure another interface but can this be accomplished with NAT??? Please help.
