ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv3
The VPN firewall provides three DHCPv6 options for the LAN. The following sections provide
information about the DHCPv6 options for the LAN:
• Concept: Stateless DHCPv6 Server Without Prefix Delegation for the LAN
• Concept: Stateless DHCPv6 Server With Prefix Delegation for the LAN
• Concept: Stateful DHCPv6 Server for the LAN
Concept: Stateless DHCPv6 Server Without Prefix Delegation for the LAN
The IPv6 clients in the LAN generate their own IP address by using a combination of locally
available information and router advertisements from the Router Advertisement Daemon
(RADVD), but receive DNS server information from the DHCPv6 server.
In a stateless DHCPv6 server configuration without prefix delegation, the RADVD advertises
the following advertisement prefixes:
• If you enabled the ISP DHCPv6 server to assign a prefix through prefix delegation to the
VPN firewall, the advertisement prefixes that are based on the ISPs assignment.
• Advertisement prefixes that you add manually for the RADVD.
For stateless DHCPv6 without prefix delegation, you must enable and configure the RADVD.

To set up a stateless DHCPv6 server without prefix delegation in the LAN, complete
these tasks:
1. Enable the ISP DHCPv6 server to assign a prefix through prefix delegation to the VPN
firewall (see Use a DHCPv6 Server to Configure an IPv6 Internet Connection
Automatically on page 90). This task is optional (see also
2. Configure the stateless DHCP server without prefix delegation (see
DHCPv6 Server Without Prefix Delegation for the LAN
3. Enable and configure the RADVD (see
the LAN on page 172).
4. If you did not enable the ISP DHCPv6 server to assign a prefix through prefix delegation to
the VPN firewall, manually add advertisement prefixes to the RADVD (see
Automatically Added Advertisement Prefixes for the LAN and Manually Add Advertisement
Prefixes on page 176).
Note: If you do enable the ISP DHCPv6 server to assign a prefix through prefix
delegation to the VPN firewall, you still can manually add advertisement
prefixes to the RADVD.
Concept: Stateless DHCPv6 Server With Prefix Delegation for the LAN
As an option for a stateless DHCPv6 server, you can enable prefix delegation. Note that this
is prefix delegation by the DHCPv6 server in the LAN, not by the ISP DHCPv6 sever in the
WAN. After you specify a prefix and a prefix length for the DHCPv6 server, the VPN firewall's
stateless DHCPv6 server assigns prefixes to its IPv6 LAN clients through the RADVD.
