Interface Properties
Interface Name This field is read-only if you are editing an existing VLAN interface. Enter the
number of the VLAN interface. You can use a number from 0~4094. See
Chapter 43 on page 591 of the User’s Guide for the total number of VLANs you
can configure on the ZyWALL. For example, vlan0, vlan8, and so on.
Zone Use this field to select the zone to which this interface belongs. This controls
what security settings the ZyWALL applies to this interface.
Base Port Select the Ethernet interface on which the VLAN interface runs. This sets which
port the VLAN’s traffic goes through.
VLAN ID Enter the number for the Virtual LAN IDentification tag. This 12-bit number
uniquely identifies each VLAN. Allowed values are 1 - 4094. (0 and 4095 are
reserved.)
Description Enter a description of this interface. It is not used elsewhere. You can use
alphanumeric and
()+/:=?!*#@$_%-
characters, and it can be up to 60
characters long.
IP Address
Assignment
Get
Automatically Select this if this interface is a DHCP client. In this case, the DHCP server
configures the IP address, subnet mask, and gateway automatically.
Use Fixed IP
Address Select this if you want to specify the IP address, subnet mask, and gateway
manually.
IP Address This field is enabled if you select Use Fixed IP Address .
Enter the IP address for this interface.
Subnet Mask 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.
Gateway 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.
Metric 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.
Interface
Parameters
Egress
Bandwidth 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
setting is used in WAN load balancing and bandwidth management.
Ingress
Bandwidth 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.
MTU 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.
