New SN SSL VPN Client behavior

This section lists the changes made to the automatic behavior of the SN SSL VPN Client when it is updated from the latest available version 3 to 4.0.9.

Changes introduced in version 4.0.5 EA

• Address book - The address book format has been changed to increase security on SN SSL VPN Client version 4. This new format is not compatible with lower versions. For more information, refer to the section Limitations and explanations on usage in the technical note Configuring and using the SSL VPN on SNS firewalls.

• Compatibility - SN SSL VPN Client is no longer compatible with Windows 8.1.

• Certificates:

  • As the SHA-1 and MD5 algorithms make it possible to sign certificates that are obsolete, they will no longer be supported in a later version of SN SSL VPN Client. It is essential for administrators to update their certificates immediately. Refer to the procedure in the article on How can I regenerate the sslvpn-full-default-authority? in the Stormshield knowledge base.

  • The SN SSL VPN Client installation folder in version 4 has been changed. During the initial connection, some users will need to indicate once again that the SNS firewall certificate has to be trusted.
