Hi guys, got an issue with Sonicwall's SSL VPN and it's security, I can connect fine to the SSL VPN, but can't remote desktop to my business PC with my mac. It’s relatively easy to use equinux’s VPN Tracker to connect to a SonicWALL. But it’s always been a headache to connect a Mac OSX computer, to a SonicWALL firewall. It’s relatively easy to connect a Windows machine/client, to a SonicWALL firewall using their free Global VPN Client.

Here’s why it’s broken and how to fix it. Dell SonicWall NetExtender 8.0.785 is broken on OSX 10.11 El Capitan.
