Configure Firewall

If you have purchased the Firewall option in Order Management, you can configure it under Security for Outbound Links, VPN-to-VPN Links, S-NAT Links, S-PAT Links and Managed Services Links.

  1. Activate the firewall for the selected group.

    • You have the option of using a predefined firewall profile that you can customise later.
    • Here, you can temporarily disable the firewall without losing the configuration, e.g. to trouble-shoot.

  2. You can adjust any rule of the firewall, add new rules or delete existing rules.

    • The firewall is a stateful port-based firewall with four levels: strong, medium, weak and user-defined.
    • By default, all ports are automatically connected from the Internet to the LAN and all ports are open from the LAN to the Internet.
    • With the firewall, you can also close the outgoing ports and thus increase security for your network.
    • The connections are also monitored (stateful), and it is ensured that the connection is always established from the LAN.
    • The weaker the firewall setting, the more ports remain open.
    • With the user-defined setting, you can individually configure all ports and tailor them to your requirements.
    • The predefined firewall rulesets are listed in the table below:
      • 1 means that a connection from the LAN to the Internet is permitted.
      • 0 means that a connection from the LAN to the Internet is blocked.
