[FreeNX-kNX] Workstation without Fixed IP as FreeNX server

[LROUFAIL at nc.rr.com]

This may have been discussed before.  I would like to have the
capability of having a workstation without a static IP be accessed as a
freenx server.

I don't know a lot about networking, but I was thinking I could use some
kind of proxy (maybe SOCKS or a VPN) to give the workstation a static
external address.

Is this possible with the nx software, or with an external program on Linux?

Thanks,

Lawrence
