Hello,

I am in the initial process of setting up OWA & OMA (Direct Push) for my
organisation. I have a pretty good idea of what needs to be done, but am a
little confused on the initial firewall/A record setup and how OMA & OWA sit
together on the same server.

Our firewall at present port forwards all port 25 data to our exchange
server - For OWA and OMA would it be a similar matter of setting up an A
record for our current external IP address and pointing port 443 to our
front end server? We do have more external IP addresses available if
necessary. How will the server differentiate between OWA and OMA requests?
Is this something that can be configured through IIS?

Thanks in advance
