ISA and SourceNAT



Dear ISA Wizards,

today I was trying to publish a mailserver in a perimeter network with ISA 2006. I found out that the outgoing smtp packets are translated to the first external ip address of the isa server itself and not to the additional ip address that is configured in the listener of the mail-server publishing rule.
The website isaserver.org states that this is true for ISA 2000 and can't be changed even by use of the wspcfg.ini.

Is this still true for the ISA 2006? As a former checkpoint firewall SE I simply can't believe that as it renders the ISA almost useless for being the frontline firewall.

Can someone please shed some light on this question?

TIA
