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 Configure ISATAP Automatic 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
