Thanks ! Works like a charm (N800/2008).

I only had to open a pinhole from blue to green network so ssh was allowed !

I guess you already think about it but just in case :

* Some options for configuring applications allowed
* An option for having a certificate on the N800 to avoid user/pass
* As said fnordianslip, this could lead to really nice & mighty putty-like app.

GREAT idea and weldone. Thanks.
