So it is correct. You had to make the ssh yourself. The Linux tightvnc
client does this for you. Anyway, it seems that the best cluent will
probably turn out to be the nomachine.com free client.

The intermediate machine is more of a gateway, which will not be running
X or the desktop of interest. If the NAT sees the intermediate machine
as the destination of an external access (i.e., the XP PC at home), then
ssh and other ports get to the intermediate machine. However, this
machine is not the ultimate destination. It can connect to the ultimate
destination machine on any required ports, and then pass the info back
out into the world on the ports the NAT allows.

I think it looks that way. I expect to set up a freeNX server on the
internal linux box that will allow remote gui logins. And use the
nomachine free client as the external client.

But I am still fuzzy on the intermediate machine. I do not see the
people using this at home setting up VPNs. But maybe the winders
software for this is easy to use...
