  • Subnet of network used in tunnel will be displayed on hovering over netwok name.
  •  Admin authentication can now be done using LDAP and Active Directory. You no longer need to maintain multiple user database even for administration of your firewall. You can now use your existing infrastructure to do so. For more details on how to achieve this, visit -
