Action required: Apply the fix for SNS firewall disks.
Please follow the procedure described in the How to update my SSD Firmware - Stormshield Knowledge Base article (authentication required).
Changing IP addresses
Periodically, SN SSO Agent will perform DNS requests (PTR) to check that machines have not changed their IP addresses. If there is a new IP address, the information will be sent to the firewall.
In the settings of your DNS server, add a Reverse lookup zone (right-click on the folder) for hosts on the domain.
