Configure Isatap Automatic Tunnelling - NETGEAR ProSafe FVS318N Reference Manual

With 6to4 tunnels, IPv6 packets are embedded within the IPv4 packet and then transported
over the IPv4 network. You do not need to specify remote tunnel endpoints, which are
automatically determined by relay routers on the Internet. You cannot use 6to4 tunnels for
traffic between IPv4-only devices and IPv6-only devices.
Note: If the wireless VPN firewall functions as the endpoint for 6to4
tunnels in your network, make sure that the wireless VPN firewall
has a static IPv4 address (see
