Connecting to a SonicWall VPN from a Linux machine

The download link for the Linux client from SonicWall is here.

Go to that page, the follow the directions to log in to the Beta site as a guest (username is "demo", password is "password" - as provided on the page), then click the large NetExtender button, which will initiate a download of the latest .tgz file.

Extract it and run ./install as root (using sudo), then run the GUI. The installer has instructions to help you all along the way.

As it was remarked that most links in the existing answers were dead and not much information was available, I thought to list below some resources that still exist:

The NetExtender clients (and others) can be downloaded from the Clients Download page and installation notes are available in this Knowledge Base article. Here are the links from the above page:

• Linux 32-bits
• Linux 64-bits
• Windows .exe

Some more useful articles :

• SonicWALL VPN with FreeS/WAN using IKE (old one from 2002)

There is no special client for SonicWall. Use Openswan on your linux box, configure a tunnel between your box and sonicwall, with NAT traversal. Here are few docs:
