LABEL

DESCRIPTION

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.

 

 

IPv6 Address

These IP address fields configure an IPv6 IP address on the interface itself.

Assignment

 

 

 

Enable Stateless

Select this to enable IPv6 stateless auto-configuration on this interface. The interface

Address Auto-

will generate an IPv6 IP address itself from a prefix obtained from an IPv6 router in the

configuration

network.

(SLAAC)

 

 

 

Link-Local

This displays the IPv6 link-local address and the network prefix that the ZyWALL

address

generates itself for the interface.

 

 

IPv6 Address/

Enter the IPv6 address and the prefix length for this interface if you want to use a static

Prefix Length

IP address. This field is optional.

 

The prefix length indicates what the left-most part of the IP address is the same for all

 

computers in the network, that is, the network address.

 

 

Gateway

Enter the IPv6 address of the default outgoing gateway using colon (:) hexadecimal

 

notation.

 

 

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.

 

 

Address from

Use this table to have the ZyWALL obtain an IPv6 prefix from the ISP or a connected

DHCPv6 Prefix

uplink router for an internal network, such as the LAN or DMZ. You have to also enter a

Delegation

suffix address which is appended to the delegated prefix to form an address for this

 

 

interface. See Prefix Delegation on page 107 for more information.

 

To use prefix delegation, you must:

 

• Create at least one DHCPv6 request object before configuring this table.

 

• The external interface must be a DHCPv6 client. You must configure the DHCPv6

 

request options using a DHCPv6 request object with the type of prefix-delegation.

 

• Assign the prefix delegation to an internal interface and enable router

 

advertisement on that interface.
