[FreeNX-kNX] Tunnelling other traffic though an nx connection

[brendan powers]

Hello,
I was wondering if it is possible to tunell other traffic though an
ssh connection. I have a service running on the client side of the
session that needs to be accessed from server side of the session. Is
there a way to do standard ssh port forwarding in an nx session?

Also, is there a way run a command uppon resuming a session?

Thanks.
