This is a strange question so I am not sure how to word it but I will try.
We have a small Network with 2 servers, one Terminal Server and an Exchange 2010 Server.
We have just had a new SQL application installed by a company.
All seems ok but now they want to be able to Telnet our Terminal Server which is where they installed there program using 2 different ports, 444 and 50495. I have set them up using Port Forwarding on the Router which is fine, but now they also want to Telnet this Server/ Application internally as well which is fine except they now want to Telnet this Server/app internally using the external/wan IP.
Im confused, my question is how do I setup the router to Telnet an Internal Server using an External IP Address. He mentions ISA Server, but I dont have an ISA Server.
Any help would be appreciated.
