You can apply a separate firewall rule to each network adapter. For example, you may want to block traffic through a VPN at an office location, but not at a home location.
You can select a network adapter from a default list that is shared across firewall policies and rules. The most common adapters are included in the default list in the Policy Components list. Use the default list so that you do not have to retype each network adapter for every rule that you create.
The network adapter list eliminates the need to retype adapters for firewall rules. When you create a firewall rule, you can select a network adapter from a default list of commonly used network adapters. You can also add network adapters to the default list.
You can add a custom network adapter through a firewall rule. However, that network adapter is not added to the default list. You cannot access the custom network adapter from any other rule.
To add a custom network adapter to the network adapter list
In the console, click Policies > Policy Components > Network Adapters.
Under Tasks, click Add a Network Adapter.
In the Network Adapter dialog box, in the Adapter Type drop-down list, select an adapter.
In the Adapter Name field, optionally type a description.
In the Adapter Identification text box, type the case-sensitive brand name of the adapter.
To find the brand name of the adapter, open a command line on the client, and then type the following text:
