NAT question

[George Thomas]

I have my mail server name defined as mail.abc.com and tied to an external IP. I need users on the LAN to access mail.abc.com and this doesnt happen today because a nslookup for mail.abc.com comes up with the external IP. Since we host that server, and the external IP is being nat-ed through the same fw, i cant get to the webpage.

Assuming you are using either a pix or an ASA firewall have a look at this link -
