Assign to Bridge

Select the bridge to which the network should be assigned.

Bridge Anti-Spoofing

Select this option to enable anti-spoofing.

If anti-spoofing is enabled, only IP addresses within the Allowed IP Range can be source IP addresses for packets on this network.

Allowed IP Range

Type the range of IP addresses that should be allowed on this network.

Note: When assigning IP addresses to machines in a bridged network segment, the ZoneAlarm DHCP server allocates only addresses within the allowed IP address range.

To enable clients to move between bridged networks without changing IP addresses, configure identical IP address ranges for the desired networks, thus allowing the IP addresses to be used on either of the bridged networks.

Note: Configuring overlapping or identical allowed IP address ranges will decrease the effectiveness of anti-spoofing between the bridged networks.

Spanning Tree Protocol - Port Cost

Type the port's cost.

STP uses the available port with the lowest cost to forward frames to the root port. All other ports are blocked.

It is recommended to set a lower value for faster links.

This field only appears if the bridge uses STP.

Spanning Tree Protocol - Port Priority

Select the port's priority.

The port's priority is combined with the port's logical number to create the port's ID. The port with the lowest ID is elected as the root port, which forwards frames out of the bridge. The other ports in the bridge calculate the least-cost path to the root port, in order to eliminate loops in the topology and provide fault tolerance.

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

Note: If you select the same priority for all ports, the root port will be elected based on the port's logical number.

The default value is 128.

This field only appears if the bridge uses STP.
