GX400 and SSL VPN

I saw a post from 2013 on this but it had no responses.

I’m looking at setting up the GX400 to connect to a Sonicwall SSLVPN, in the process of doing so i found this note

Note: SSL tunnel is based on the OpenVPN open source package. AirLink devices are
SSL clients and will only talk to an SSL server (also based on the OpenVPN package).

So i’m guessing it won’t work with Sonicwall, but i wondered if anyone had gotten it to work at all?
