Network Name

Type a name for the bridge.

Firewall Between Members

Specify whether the firewall should be enabled between networks on this bridge, by selecting one of the following:

• Enabled. The firewall is enabled, and it will inspect traffic between networks on the bridge, enforcing firewall rules and SmartDefense protections. This is the default value.
• Disabled. The firewall is disabled between networks on the bridge.

Non IP Traffic

Specify how the firewall should handle non-IP protocol traffic between networks on this bridge, by selecting one of the following:

• Block. The firewall will block all non-IP protocol traffic on the bridge. This is the default value.
• Pass. The firewall will allow all non-IP protocol traffic on the bridge and process it as described in Using Bridges.

Spanning Tree Protocol

Specify whether to enable STP for this bridge, by selecting one of the following:

• Enabled. STP is enabled.
• Disabled. STP is disabled. This is the default value.

If you selected Enabled, the Bridge Priority field appears.

Bridge Priority

Select this bridge's priority.

The bridge's priority is combined with a bridged network's MAC address to create the bridge's ID. The bridge with the lowest ID is elected as the root bridge. The other bridges in the tree calculate the shortest distance to the root bridge, in order to eliminate loops in the topology and provide fault tolerance.

To increase the chance of this bridge being elected as the root bridge, select a lower priority.

Note: If you select the same priority for all bridges, the root bridge will be elected based on MAC address.

The default value is 32768.

This field only appears if STP is enabled.

IP Address

Type the IP address to use for this gateway on this bridge.

Note: The bridge must not overlap other networks.

Subnet Mask

Select this bridge's subnet mask.
