Since I had no response to my request, but did find out the solution I would like to post it here. Once the Airport Base Station is setup the outside IP address is the one from my Mac desktop computer. My desktop computer and laptop computer, that is both the LAN and the wireless networks, have their own IP addresses of 10.0.1.x. In order to make my desktop computer accessible from the Internet, I go into the Airport Administration Utility, then to Port Mapping, and enter mapping for port 80 (http) and port 554 (rtsp). The setup is as follows: Public Port = 80, Private IP Address (10.0.1.3-my desktop computer) and Private Port = 80. I do the same thing with port 554 using the same private IP address. When the outside IP is accessed the request goes directly to my desktop computer?the HREF does not need to change?just direct to outside IP address.
