ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv3
IPv6 Router Advertisement Daemon for the LAN
The RADVD is an application that uses the Neighbor Discovery Protocol (NDP) to collect
link-local advertisements of IPv6 addresses and IPv6 prefixes in the LAN. The RADVD then
distributes this information in the LAN, which allows IPv6 clients to configure their own IPv6
address.
Hosts and routers in the LAN use NDP to determine the link-layer addresses and related
information of neighbors in the LAN that can forward packets on their behalf. The VPN
firewall periodically distributes router advertisements (RAs) throughout the LAN to provide
such information to the hosts and routers in the LAN. RAs include IPv6 addresses, types of
prefixes, prefix addresses, prefix lifetimes, the maximum transmission unit (MTU), and so on.
In addition to configuring the RADVD, you also must configure the prefixes that are
advertised in the LAN RAs.
The following table shows how the VPN firewall obtains information in the LAN if you
configure a stateless DHCPv6 server and the RADVD.

Flags in the RADVD
Managed RA flag is set.
Other RA flag is set.
a. Both the DHCPv6 server and the RADVD can assign IP addresses.
When the Managed flag is set in the RADVD, the DHCPv6 server can assign IP addresses
and the RADVD also assigns IP addresses in the sense that it provides information that
allows IPv6 clients to configure their own IPv6 address.
When the Other flag is set, the DHCPv6 server does not assign IP addresses but provides
DNS server and other configuration information only.
Configure the IPv6 Router Advertisement Daemon for the LAN
The following procedure describes how to configure the Router Advertisement Daemon
(RADVD) for the LAN.

To configure the RADVD for the LAN:
1. On your computer, launch an Internet browser.
2. In the address field of your browser, enter the IP address that was assigned to the VPN
firewall during the installation process.
The VPN firewall factory default IP address is 192.168.1.1.
