Hi,

See attached example, also make sure to issue: clear xlate and save with: write mem

Make sure that your MX record IP for e-mail corresponds to the IP on your ACL for smtp. By default the PIX allows all traffic out from inside network to outside so you should be able to browse the web! Unless you are also hosting a web server on the inside then you'll need the apporiate ACL and static commands in place.

You can also test the smtp connectivity by telneting from an outside network on your public IP for smtp on port 25 to see if it connects to your internal mail server.

Hope this helps and if it does please rate post.

Hi,

Add a nat global statement to enable web/mail server to return traffic to the outside.

e.g. nat 71 0.0.0.0 0.0.0.0 outside 0 0

global inside 71 192.168.0.71

This will make all traffic from outside appear as 192.168.0.71 on the inside.

Hope that helps.
