That suggestion (not from me, but I understand it) was to create an A record for a different name, Webmail.domain.tld. So you'd have mail.domain.tld pointing to the Gateway, and webmail.domain.tld pointing to the IMail box.
I don't understand the comment "The firewall we have can't do port forwarding to the same network IP address". You want to forward IP (not port) to different IPs (not same network IP address) based on the Destination Port. In IPTABLESeese, that's: -A PREROUTING -p tcp -m tcp --dport 25 -d public.address.of.mail -j DNAT --to-destination dmz.address.of.gateway -A PREROUTING -p tcp -m tcp --dport 80 -d public.address.of.mail -j DNAT --to-destination dmz.address.of.imail ymmv, depending on your firewall. hth Dan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Leda Summer Sent: Wednesday, April 27, 2005 9:54 AM To: [email protected] Subject: RE: [IMail Forum] How do you deal with the mail gatway situation Our servers are in DMZ network. The firewall we have can't do port forwarding to the same network IP address. The mail gateway can only route per domain one IP , one port, which has to be used for mail delivering (port 25). I can see web mail from browser by type IP address, but not the mail domail name address, since in the DNS, the mail domain name is pointing to gateway IP for the purpose of sending all mail going through the gateway. I can't set up another "A" record to point to the real mail domain ip (setup in imail), since the "A" record already made mail domain name to pointo the gateway ip address. Any other route way?
