I checked already the router but as I said I use SSH in the LAN/WAN also on custom ports and never had any issues.

Indeed it seems to be a network problem, I followed your log tutorial and look at the logs at the moment. Simply nothing happens at all when I try to connect with SSH but it looks ok when I connect on the phone itself on a second console.

I have a simply LAN network here, my notebook is connected per LAN and my N900 is connected per WLAN to a router. I use on the notebook itself Windows XP and Putty for SSH connections. As I said I also tested If I can connect from my N95 but got a timeout as result, it works fine to other SSH server's from both devices.

The only application which works always fine is UltraVNC on port 5900. I simply use the N900 IP (192.168.10.114).
