It probably won't matter to your systems that live behind the firewall, as they'll be configured to send mail to/retrieve mail from the machine on the private IP. But for the purposes of the outside world, the DNS that gets fed to that outside world should be a public IP, and it should be nat'd back to your private IP. -- Mike Burger http://www.bubbanfriends.org Visit the Dog Pound II BBS telnet://dogpound2.citadel.org or http://dogpound2.citadel.org:2000 To be notified of updates to the web site, visit http://www.bubbanfriends.org/mailman/listinfo/site-update, or send a message to: site-update-request@xxxxxxxxxxxxxxxxx with a message of: subscribe -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
