I am not using a VPN to access the box at the house.
I do not have direct access to the FreeBSD box (the gotcha).
Here is a diagram that might explain things better:
I want to enable a SSH Tunnel to the OpenBSD Box that will communicate with another pre-established SSH Tunnel between the OpenBSD box and the FreeBSD box.
I have not (yet) enabled NAT/Port forwarding on the OpenBSD box.
The idea is that I want to tunnel my way all the way past the OpenBSD box into the FreeBSD box. I can setup a tunnel between the OpenBSD box to the FreeBSD box without any problems (already tested, works like a charm). This way, I never have to expose any extra ports to the world other than my already exposed SSH port. I also wanted to bypass a VPN for this. When I VPN into work from my Win2K box, all my other networks get dropped and I wanted to avoid this.
Clear as mud?
