LABEL

DESCRIPTION

IP Address

This field is enabled if you select Use Fixed IP Address.

 

Enter the IP address for this interface.

 

 

Metric

Enter the priority of the gateway (the ISP) 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)

 

 

 

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.

Edit

Select an entry and click this to change the settings.

 

 

Remove

Select an entry and click this to delete it from this table.

 

 

#

This field is a sequential value, and it is not associated with any entry.

 

 

Delegated

Select the DHCPv6 request object to use from the drop-down list.

Prefix

 

 

 

Suffix

Enter the ending part of the IPv6 address, a slash (/), and the prefix length. The

Address

ZyWALL will append it to the delegated prefix.

 

For example, you got a delegated prefix of 2003:1234:5678/48. You want to configure

 

an IP address of 2003:1234:5678:1111::1/128 for this interface, then enter

 

::1111:0:0:0:1/128 in this field.

 

 

Address

This field displays the combined IPv6 IP address for this interface.

 

Note: This field displays the combined address after you click OK and reopen this

 

screen.

 

 

DHCPv6 Setting

 

 

 

DHCPv6

Select Client to obtain an IP address and DNS information from the service provider

 

for the interface. Otherwise, select N/A to diable the function.

 

 

DUID

This field displays the DHCP Unique IDentifier (DUID) of the interface, which is unique

 

and used for identification purposes when the interface is exchanging DHCPv6

 

messages with others. See DHCPv6 on page 107 for more information.

 

 

DUID as MAC

Select this if you want the DUID is generated from the interface’s default MAC address.

 

 

Customized

If you want to use a customized DUID, enter it here for the interface.
