Manage VPN Firewall Rules


  • Click 'Firewall' > 'VPN traffic' in the left-hand menu to open the VPN firewall policy interface
  • Dome Firewall supports two types of VPN traffic – SSL VPN and L2TP / IPSec
  • SSL VPN – You need to configure SSL VPN server, add client accounts and install OpenVPN clients on endpoints. See 'SSL VPN Server' and its subsections for more details
  • L2TP / IPSec – You need to configureL2TP server, IPSec connection type and add IPSec / L2TP users
    • After configuring them, SSL VPN server, SSL VPN user accounts and IPSec connections will become available as firewall objects. These objects can be used to populate 'source' and 'destination' fields in various interfaces.
      • Note – Create rules for network FW traffic in 'Firewall' > 'Policy' for easy management of internal and external networks FW rules. See 'Manage Firewall Policy Rules' for more details.


      • Current Rules - Current Rules - Lists all currently active rules and allows you to add and edit rules. See Manage VPN Traffic Rules for more details on viewing and managing the rules.
      • VPN Firewall Settings - Enable or disable the firewall. Choose whether you want to log all VPN connections which get allowed by the firewall policy. See Configure the VPN Firewall Settings for more details.
