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 66.67.68.69 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.

Use port forwarding for the type of request its listening for. If its FTP, forward port 21 to that internal local IP... and so on.. etc.
