I have several VPN's that I need to establish on a daily basis but from multiple workstations.

What I would like to do it have either a server or vpn router that can perform this connection itself and that I can then route traffic through this device or server depending on the subnet I am trying to reach.

The issue is that I only use VPN Clients to connect, so I am basically trying to achieve almost a site to site VPN but by using basically a VPN Client type connection from my network.

The main VPN Client I use is the Sonicwall Global VPN Client where I initially use a Preshared Key and then it always prompts me for a username and password (not RSA key).

My question is, is there any type of linux distro or even a hardware vpn router that can do this and connect to a Sonicwall device as if it were a client?

I have tried pfSense which is very good but it fails to connect, probably due to a mismatch of settings.

I have tried many others. Even dd-wrt on my router but it does not support whatever protocol Sonicwall uses. (I thought L2TP/IPSec) but it appears it may not be that.

Any advice would be great!

The other other thing I have thought of that I have not tried yet is Windows Server Routing and Remote Access but I have a feeling that won't work either.

Thanks
