LAN
An IPv6 LAN typically functions with site-local and link-local unicast addresses. Each
physical interface requires an IPv6 link-local address that is automatically derived from the
MAC addresses of the IPv4 interface and that is used for address configuration and neighbor
discovery. (Normally, you would not manually configure a link-local address.)
Traffic with site-local or link-local addresses is never forwarded by the wireless VPN firewall
(or by any other router), that is, the traffic remains in the LAN subnet and is processed over
the default VLAN only. A site-local address always starts with FEC0 (hexadecimal); a
link-local unicast address always starts with FE80 (hexadecimal). To forward traffic from
sources with a site local or link-local unicast address in the LAN, a DHCP server is required.
For more information about link-local unicast addresses, see
Tunneling
on page 47.
Because each interface is automatically assigned a link-local IP address, it is not useful to
assign another link-local IP address as the default IPv6 LAN address. The default IPv6 LAN
address is a site-local address. You can change this address to any other IPv6 address for
LAN use.
Note:
Site-local addresses, that is, addresses that start with FEC0, have
been depreciated. However, NETGEAR has implemented a
site-local address as a temporary default IPv6 LAN address that you
can replace with another LAN address. The firewall restricts external
communication of this default site-local address.
DHCPv6 Server Options
The IPv6 clients in the LAN can autoconfigure their own IPv6 address or obtain an IPv6
address through a DHCPv6 server. For the LAN, there are three DHCPv6 options:
Stateless DHCPv6 Server
The IPv6 clients in the LAN generate their own IP address by using a combination of locally
available information and router advertisements, but receive DNS server information from the
ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N
on page 186).
