Firewall Rule List Interface and Icons

The features and controls of the configuration pages for the Host and Forwarding Firewall rulesets have a similar interface structure. The main rules section in these pages displays the access or application rules depending on the selected ruleset in the left menu. You can view, create, copy, paste, clone, and edit your access rules on this page.

The Forwarding Firewall Ruleset

The Forwarding Firewall ruleset contains all forwarding access and application rules and provides access to the access and application rule configuration dialog. To open the Forwarding Firewall ruleset, go to CONFIGURATION > Configuration Tree > Box > Assigned Services > Firewall > Forwarding Rules.

The Forwarding Rules page is divided into the following sections:

For more information on the functionalities of the Forwarding Firewall ruleset, see Forwarding Firewall.

Firewall Objects

Firewall objects are used to reference networks, services, applications, user groups, or connections in order to simplify the management and maintenance of rules and network setups. You can use predefined and custom objects when configuring routes, or when creating access- and application rules. For more information, see Firewall Objects.

Host Access Ruleset

The host access ruleset contains default rules that fit most applications and services that are handled by the Barracuda CloudGen Firewall. Changing the host access ruleset should only be done by an expert administrator because changes can affect the behavior of your system. For help with changing default host access rules, contact Barracuda Networks Technical Support.

You can view the host access ruleset on the Host Firewall - Rules page. To open this page, go to Config > Box > Infrastructure Services > Host access rules.

The Host Firewall - Rules page provides an interface very similar to the Forwarding Firewall and is divided into the following sections:

  • Configuration Menu – The left navigation pane of the page provides you with menu sections to configure your access rules.

  • Inbound and Outbound Table – In the table, you can view and edit the settings for all inbound and outbound host access rules. To switch between viewing the inbound and outbound rulesets, click the following tabs:

    • Inbound – Shows all inbound host access rules.

    • Inbound-User – (Bound to the Inbound set) Shows a subset of inbound host access rules.

    • Outbound – Shows all outbound host access rules.

    • Outbound-User tab – (Bound to the Outbound set) Shows a subset of outbound host access rules.
