Chapter 9 Interfaces Table 119 Configuration > Network > Interface > Bridge > Add / Edit (continued) LABEL DESCRIPTION IPv6 Address/ Prefix Length Enter the IPv6 address and the prefix length for this interface if you want to use a static IP address. This field is optional. Gateway Metric Address from DHCPv6 Prefix Delegation The prefix length indicates what the left-most part of the IP address is the same for all computers on the network, that is, the network address. Enter the IPv6 address of the default outgoing gateway using colon (:) hexadecimal notation. 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. 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 Prefix Delegation on page 242 for more information. To use prefix delegation, you must: Add Edit Remove References # Delegated Prefix Suffix Address • 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. Click this to create an entry. Select an entry and click this to change the settings. Select an entry and click this to delete it from this table. Select an entry and click References to open a screen that shows which settings use the entry. See Section 9.4.4 on page 265 for an example. This field is a sequential value, and it is not associated with any entry. Select the DHCPv6 request object to use from the drop-down list. Enter the ending part of the IPv6 address, a slash (/), and the prefix length. The Zyxel Device will append it to the delegated prefix. Address 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. This field displays the combined IPv6 IP address for this interface. DHCPv6 Setting DHCPv6 DUID DUID as MAC Note: This field displays the combined address after you click OK and reopen this screen. Select N/A to not use DHCPv6. Select Client to set this interface to act as a DHCPv6 client. Select Server to set this interface to act as a DHCPv6 server which assigns IP addresses and provides subnet mask, gateway, and DNS server information to clients. Select Relay to set this interface to route DHCPv6 requests to the DHCPv6 relay server you specify. The DHCPv6 server(s) may be on another network. 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 243 for more information. Select this if you want the DUID is generated from the interface's default MAC address. ZyWALL ATP Series User's Guide 312
