[FreeNX-kNX] Unexpected timeout connecting

[Colin McKinnon]

Hi all,

I'm trying to setup freeNX and am having some problems.

I've got a clean install of debian (from Knoppix, then upgraded). I can 
connect to the server running the client on the same machine, but when I try 
to connect from a remote client, I get a timeout error.

- I can ssh into the remote server
- turning off the firewall on the server doesn't improve things
- nor does enabling "SSL encryption of all traffic"

The connection log is shown below.

nxclient reports "Authentication completed" in less than 1 second, then about 
30 seconds later "Connection timeout".

It may be relevant that I'm getting the error while running the client behind 
a masquerading router (server is directly plugged into internet) but I thought 
that 'SSL encryption of all traffic' would obviate any issues arising from 
that.

Anybody any ideas?
TIA,

Colin
