I’m a little confused on how email will reach the email server which is in the inside interface. Can someone please look at this config and answer the questions below?
1. Which IP will I use to point to my domain (A Record for InterNic)? Is it the public ip of the IIS server since that is where the website is or is it the IP of the outside interface on the pix?
2. How will emails reach the email server since it is in the inside? I'm thinking its
this* static (inside,outside) tcp interface smtp 192.168.50.5 smtp netmask 255.255.255.255 ?
3. Will this config do the following
a. Access the web server in the dmz.
b. Allow OWA to reach email server(inside).
c. Allow all host to access the internet including the server in the dmz.
