Do you need to map a specific TCP or UDP port on your machine to another port on another machine Do you want to limit access to a server on your machine based on the IP address of an incoming connection request If these sound interesting to you, then AnalogX PortMapper is just what the doctor ordered (or programmer, in this case). AnalogX PortMapper allows you to map and port on your computer to any IP address and port on another machine; not only that, you can limit access based on the incoming IP address! So, say for instance that you are using a proxy, and would like to be able to telnet from other machines; simple, just run PortMapper, and tell it to forward any request to port 23 (telnet) to the machine you want to access. Now, any time you telnet to your proxy server machine, it automatically forwards the data to the other machine! Or, do you run a webserver, and only want people from IP address you specify to connect No problem, PortMapper can do that as well! Overall, a great standalone program, or an excellent addition to a proxy or server!
PortMapper works on all versions of Windows, from Window 95 to Windows 7 and everything inbetween (including XP, Vista, Win2k, etc).
AnalogX PortMapper allows you to map and port on your computer to any IP address and port on another machine; not only that, you can limit access based on the incoming IP address! Here is an example: Let`s say you have a web server running on machine2 but no Internet connection for that machine. People could still access the web server (or any other server) on that machine if you run Portmapper on (online) machine1 and direct all incoming requests for port 80 to the IP address of machine2. It`s like Call Forwarding for servers.
