Thank you so much for your response and giving me the input on doing this mapping. Apparently it is not working. I follow all your step, but so far nothing. When I create the "server publishing rule", I can't find "telnet" the only thing close to it is "telnet server", so I choose that. When I run the program, it stated the IP address of the other external. I have external address of 200.200.200.1 (which is for any other traffic) and 200.200.200.10 (which is for mapping), I setup the second one using the "advance" on the IP configuration. I have the internal PC address at 192.168.200.100. When I run the program, it states that my IP address is 200.200.200.1, instead of the 200.200.200.10 that I need it to be. Any other suggestion? Thank you in advance for your time.
