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
Assignment
These IP address fields configure an IPv6 IP address on the interface itself.
Enable Stateless
Address Auto-
configuration
(SLAAC)
Select this to enable IPv6 stateless auto-configuration on this interface. The interface
will generate an IPv6 IP address itself from a prefix obtained from an IPv6 router in the
network.
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
DHCPv6 Prefix
Delegation
Use this table to have the ZyWALL obtain an IPv6 prefix from the ISP or a connected
uplink router for an internal network, such as the LAN or DMZ. You have to also enter a
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.

Delegated
Prefix
Select the DHCPv6 request object to use from the drop-down list.
Suffix
Address
Enter the ending part of the IPv6 address, a slash (/), and the prefix length. The
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
