Destination NAT on ASA

[melchib]

Hi,

I am trying to configure an ASA (8.0.3) to intercept all smtp traffic coming from a dmz greylisting smtp server and then re-write the destination ip to the inside smtp server.

For example my dmz greylist smtp server has an ip of 192.168.1.25 and is trying to send smtp out to Internet host 1.1.1.25 - I'd like to intercept that and re-write the destination ip to my inside host of 10.1.1.25 and then let him process the smtp packet.

Is this possible with the ASA?

Thanks!

Brad

Should look something like this...

static (inside,dmz) 1.1.1.25 10.1.1.25 netmask 255.255.255.255

Ok...I got that if I'm just interested in rewrtiting for a single host. What I'm looking to do is if 192.168.1.25 sends to any host on tcp port 25 to rewrite the destination to 10.1.1.25. Unfortunately the static statement doesn't allow an 'any' keyword eg.:

static (inside,dmz) tcp any 25 10.1.1.25 25 netmask 255.255.255.255
