What is it you want to be accessible? You want to be able to access the terminal in it from anywhere? If so, sounds like a job for SSH. You can forward the SSH port (default is 22, but not a bad idea to change it in the SSH config and then forward that new port). Once the port is forwarded you should be able to do ssh user@external.ip.address, etc. Then you'll get a prompt. Highly recommended you set up SSH keys instead of using regular passwords. Hope this helps.
