Gateway
This field is enabled if you select
Use Fixed IP Address
.
Enter the IP address of the gateway. The Zyxel Device 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 (the ISP) on this interface. The Zyxel Device 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 Zyxel Device 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 Zyxel Device 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 Zyxel Device uses the one that was configured
first.
Address from
DHCPv6 Prefix
Delegation
Use this table to have the Zyxel Device 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
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.

#
This field is a sequential value, and it is not associated with any entry.
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 Zyxel Device
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 disable 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
for more information.
