accessing a computer through telnet

you have to forward the port (25) to a particular PC. You can't do the same one to all, but you can telnet to any port, so you would forward other ports to 25 on the other 2 machines (above 3000 for example)

<i>It's always the one thing you never suspected.</i>

What jlanka is telling you is that when you forward a port on your router, you can forward it to only one ip address and therefore to only one computer. So if you wish to access your 3 computers using Telnet, then you will need to take 3 ports and forward each one to a different IP.

In ancient times they had no statistics so they had to fall back on lies
