Hi I have a problem with NATing and Pix. I have a Linux machine doing mail scanning on the inside network. I am forwarding all mail on port 25 to this machine. However this machine is also acting as a firewall for another internet connection and is placing all reply traffic coming from outside the Pix on it's gateway instead of the Pix.
My question is whether I can translate the external mail IP addresses (which are random) and make the Linux machine see them as being internal IP address(es) so it can respond locally to them. Currently it sees them as public IP connections on port 25 and responds out it's gateway. I have the usual: static(inside,outside)external_mail_ip internal_mail_ip
access-list permit tcp any external_mail_ip eq 25 (applied to external interface)
Any pointers appreciated thanks
