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.
