LABEL

DESCRIPTION

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 50 on page 749 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

Select this if this interface is a DHCP client. In this case, the DHCP server

Automatically

configures the IP address, subnet mask, and gateway automatically.

 

You should not select this if the interface is assigned to a VRRP group. See

 

Chapter 34 on page 575.

 

 

Use Fixed IP

Select this if you want to specify the IP address, subnet mask, and gateway

Address

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

Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can

Bandwidth

send through the interface to the network. Allowed values are 0 - 1048576. This

 

setting is used in WAN load balancing and bandwidth management.

 

 

Ingress

This is reserved for future use.

Bandwidth

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.
