I saw a post in January that attempted to answer this question and I followed the advice, but to no avail.

Here is my configuration. I have 5 public IPs (.248 subnet). The outside interface is set as I have an internal network My exchange server is and its Public IP is

I want accept smtp only from Messagelabs that directs our email to the .36 address.

Right now every thing works except incoming e-mail and the VPN. Any suggestions would be helpful. Here is my config.
