title: How to telnet to a computer which is sharing a single public ip?
body: <p>Suppose that I am sharing a public ip 56.162.XXX.XXX with some other users. Now I have a local ip that I see if I type ipconfig in the command prompt. That is 192.168.2.3. Now I have a program running on port 3630 listening to any incoming connection. I can call myself with the help of loop back ip ie. telnet 127.0.0.1 3630, and i see that two programs are getting connected and can exchange data. I can also telnet and get connected with my laptop from another laptop which is sharing same public ip as mine by the command telnet 192.168.4.20 3630. But how should I do the same from a remote computer? I mean a computer which has a different public ip.
  Actually I want something like "telnet public ip(local ip) port no". The other computer is also sharing a public ip with some other users.</p>
