sure i can. it was actually easier than I thought. To do that I had to register for a domain name, and set my domain name to the static ip representing my server. (I configured my router earlier to give a static ip to this specific box every time it reboots) Then everything follows, all i had to do to try this out is to open up my ssh or telnet, and enter the domain name , username, password and then login.
one more thing is you might need to open up ssh , telnet, and ftp ports so remote pc can come in the server through the specific port.
hope that helps ppl trying to learn like me ==*
