[FreeNX-kNX] Printen to private network

Thanks Alastair,
I think this config is the same as the default config from the last version nx?..
except the cups 1.1.x on my Fedora core5 server
But for sure if it can work.... (before is trash my yum/rpm database with --force --nodeps)
- my server is at a hosting provider far away :-) on an public ip.
- different thin clients need to print trough the NX server to their thinclient-printer
The thin clients are in a private 192.168.1.x network.
So this is possible via the ssh-tunnel?
