Setup: I have a Cisco 877 ADSL Router that is configured with a single Static Public IP address. I also have a Windows SBS 2003 on the LAN that I want to access via the internet for OWA and RPC over HTTP. The server has a single IP address of 192.168.20.10.
Question. How can I configure the Cisco to map multiple ports to a single internal IP address? I am trying to do this in SDM, but it will not allow me to map more than one port to the same internal IP address.
P.S. If you are suggesting a solutions that requires editing the configuration without SDM, please be specific about where and how to enter the configuration changes since I am not familiar with Cisco.
