accessing an internal network via internet
Is there a way to access a computer on a local network via the internet (i.e. access an ftp server at 192.168.0.1 on the local network via the host at 18.104.22.168 on the internet)? I would assume that I would have to change my routing somhow to reach the local computer via the host, but don't know how. I won't need access to any other computers on the network besides that one. The computer on the local network is currently running winbloze, but I could install Cygwin on it if I would need to use a Linux application to allow this.
