Ubuntu VPN tunnel & Linksys VPN Router

[ikus060]

Hi,

I'm buy a while ago a VPN Router (Linksys RV042) and I never manage to get the VPN working. So far I continue to use SSH tunnel, but I have some different need know and want to get the VPN working.

I'm not a VPN expert and get some problem to determine why I cannot get it working.
The first step would be to set the VPN configuration and then setup the client.

So here the VPN config :
