  • RPC over HTTP with mail gatway

    we have in our organization exchange server 2003.
    we also have a mail gateway running on Debian with postfix.
    the mail gateway is the exposed host .
    the exchange doesn't have external ip.
    to get the owa we set a nat on our firewall.

    now we want to configure the exchange to work RPC via HTTP.
    is it possible with this configuration? is it possible with no external ip for the exchange?

        I wonder if it's possible to NAT the required ports to your Exchange box.

        I'll have a search on to see if I can find anything

            this is the same type setup i have in place currently. all mail is routed thru a hardware mail gateway. none of the exchange servers in my org have a public IP. after lisening to sembee, its gonna stay that way too...

            every workstation sends mail to the BE box, and it in turn sends it out the ironport (my mail gateway). on the side there is a front end server... it is simply there to provide the OWA and the RPC for some employees. this box is located internally and it has a staticly NATed address to the outside... everything works like a pro. the ironport is internal as well, and has port fowarding for 25 thru the firewall... and thasts it.
            its easier to beg forgiveness than ask permission.

              If you want to use RPC over HTTP, then you will need to have a connection to the Exchange server.
              You will also need an SSL certificate to use it.

              The connection to Exchange can either be direct - by opening port 443 to the internet, or via a compatible proxy. That pretty much means an ISA server.

              If you already have NAT for OWA, then you don't need to do anything else. Hopefully you are using SSL with OWA (if not why not).
