DNAT Mailserver to DMZ proxy

Darryl Smith
G'Day, and HELP...

I want to DNAT incoming packets coming direct to my mail server, to go through the proxy. 

The way I understand it, if I DNAT on SMTP for ANY to go to the firewall, this will crate a problem when the firewall itself attempts to send mail to the mail server.

Is there an easy way around this? Am I missing something. 

Many thanks

Darryl

    Hy Darryl, 

    i take a shot in the dark, 
    if you redirekt the ip specified in the MX record of your domain 

    'MX Domain IP' 'SMTP' 'External Interface' 'SMTP'
    and an SMTP route 'Domain' -> 'local mail server ip'

    i think every mail for this domain should go through the firewall.

    hope that helps, 
    kind regards, 
    gert
