Hi,

With the newer sonicwall 5.9+ os, there’s minor differences when you setup the SSL VPN from previous OS.

Not so tricky, but, when I try to login from a windows 8.1 machine I face an SSL error with the self signed ?

please make sure the server has valid certificate …

You need to change the following settings :

SSL VPN -> Server Settings -> Check Enable Server Cipher Preferences -> Select : 3DES_SHA1.

Reconnect and work….. Cheers..
FYI on the Mac the connection was working with the default settings.
