we have an exchange server 2003SP2 running in windows server 2003 ..we are running the exchange in a single server but its is integrated with our ADS. The exchange computer name is myexserver.mydomain (mydomain is single label domain name of our ADS ). The OWA is running in IIS in the default website under a virtual directory called exchange we can access this website through http://myexserver/exchange
. we are configured a NAT in our router to expose the OWA through our public IP.
we are in the middle of installing RPC over HTTP/s in the server, because we need to get exchange access from outlook through WAN without VPN.I have checked in the exchange server and can see that there is already the RPC over HTTP proxy component is installed and can see the RPC over HTTP tab under my server properties in exchange system manager but it is not enabled.
Here are my questions
1 Is there any issues the can be occurred when enabling the RPC over HTTP proxy in exchange server?
2 I can see the RPC virtual directory under the default website in IIS and the default website is already port forwarded (NAT) in firewall to get OWA from external. How I can configure the firewall to get RPC proxy outside access? .There is a domain name already mapped to our public IP for ftp access ftp.mycompany.com
3 can I use the public IP in as proxy server in the outlook client when configuring exchange account from outside my domain?
4 can I use the GUI in exchange system manger to configure RPC over HTTP or do i need the manual modification in the registry?
