Hi,
my scenario: My mailserver is inside the internal network (192.168.2.x). At the dmz there is a smtp gateway (viruswall) (192.168.1.x).
Now I want my mailserver to forward all mail to the viruswall. With a smarthost it does not work.
Is it a problem of SNAT? The gateway of my mailserver is ASL. Can I forward port 25 from ASL to the viruswall?
Thanks for help.
