DESCRIPTION
This field displays Ethernet interfaces and VLAN interfaces that can become
part of the bridge interface. An interface is not available in the following
situations:
• There is a virtual interface on top of it
• It is already used in a different bridge interface
Select one, and click the >> arrow to add it to the bridge interface. Each bridge
interface can only have one VLAN interface.
This field displays the interfaces that are part of the bridge interface. Select one,
and click the << arrow to remove it from the bridge interface.
Select this if this interface is a DHCP client. In this case, the DHCP server
configures the IP address, subnet mask, and gateway automatically.
Select this if you want to specify the IP address, subnet mask, and gateway
manually.
This field is enabled if you select Use Fixed IP Address.
Enter the IP address for this interface.
This field is enabled if you select Use Fixed IP Address.
Enter the subnet mask of this interface in dot decimal notation. The subnet
mask indicates what part of the IP address is the same for all computers in the
network.
This field is enabled if you select Use Fixed IP Address.
Enter the IP address of the gateway. The ZyWALL sends packets to the
gateway when it does not know how to route the packet to its destination. The
gateway should be on the same network as the interface.
Enter the priority of the gateway (if any) on this interface. The ZyWALL decides
which gateway to use based on this priority. The lower the number, the higher
the priority. If two or more gateways have the same priority, the ZyWALL uses
the one that was configured first.
Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can
send through the interface to the network. Allowed values are 0 - 1048576.
This is reserved for future use.
Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can
receive from the network through the interface. Allowed values are 0 - 1048576.
Maximum Transmission Unit. Type the maximum size of each data packet, in
bytes, that can move through this interface. If a larger packet arrives, the
ZyWALL divides it into smaller fragments. Allowed values are 576 - 1500.
Usually, this value is 1500.
Select what type of DHCP service the ZyWALL provides to the network.
Choices are:
None - the ZyWALL does not provide any DHCP services. There is already a
DHCP server on the network.
DHCP Relay - the ZyWALL routes DHCP requests to one or more DHCP
servers you specify. The DHCP server(s) may be on another network.
DHCP Server - the ZyWALL assigns IP addresses and provides subnet mask,
gateway, and DNS server information to the network. The ZyWALL is the DHCP
server for the network.
