Configuring a DHCPv6 Server

This section describes how to configure a DHCPv6 server.

Prerequisites

Choose Dashboard > Device Information and enable IPv6 globally to allow the FW to forward IPv6 packets.

Context

A DHCPv6 server globally maintains parameters, such as IPv6 addresses, prefixes, and information leases. DHCPv6 also assigns configuration information, such as the IPv6 addresses of DNS and SIP servers, to DHCPv6 clients.

Procedure

Choose Network > DHCP Server > Settings.
Click Add.

Set the following basic DHCPv6 server parameters.

Parameter	Description
Interface Name	Name of the interface on which the DHCPv6 server function is configured. The interface must be an existing interface, and its Connection Type must be set to Static IP.
Type	Protocol type on the interface: IPv4: enables DHCP. IPv6: enables DHCPv6. Select IPv6 in this example.
Service Type	Enable server service on this interface.
(Optional)Primary DNS Server	Primary DNS server address to be assigned to a DHCPv6 client.
(Optional)Secondary DNS Server	Secondary DNS server address to be assigned to a DHCPv6 client.

Click Add in Delegated Prefix. In the dialog box, click OK, and set parameters for the address pool.

Set basic parameters of the network address pool.

Parameter	Description
Type	Type of a DHCPv6 prefix pool. To configure the DHCPv6 address pool type, select Network Address.
Prefix	IPv6 prefix address/prefix length.
Lease Duration	Lease duration of the network prefix. Use Unlimited or set a specific lease period.

Parameter

Description

Type

Type of a DHCPv6 prefix pool.

To configure the DHCPv6 address pool type, select Network Address.

Prefix

IPv6 prefix address/prefix length.

Lease Duration

Lease duration of the network prefix.

Use Unlimited or set a specific lease period.

Click Add in Static Prefix Binding. In the dialog box, click OK, and statically bind a DHCPv6 prefix to a DUID.

Parameter	Description
Address	IPv6 prefix. An assigned IPv6 prefix is reserved for the client and cannot be assigned to another client.
DHCPv6 Client DUID	Client DUID that the DHCPv6 server uses to identify a client.
Lease Duration	Lease duration of the bound entry. Select Unlimited or set a specific lease period.

Parameter

Description

Address

IPv6 prefix.

An assigned IPv6 prefix is reserved for the client and cannot be assigned to another client.

DHCPv6 Client DUID

Client DUID that the DHCPv6 server uses to identify a client.

Lease Duration

Lease duration of the bound entry.

Select Unlimited or set a specific lease period.

Click OK.

Set the following advanced DHCPv6 server parameters.

Parameter	Description
Domain Name	DNS suffix that a DHCPv6 server assigns to a DHCPv6 client.
SNTP Server	SNTP server address that a DHCPv6 server assigns to a DHCPv6 client.
SIP Server	SIP server address that a DHCPv6 server assigns to a DHCPv6 client.

Click Apply.
Repeat previous operations to configure the DHCPv6 server function on multiple interfaces.
