Netgear FVS318N – Prosafe Wireless N VPN Firewall 快速安装指南

Enable 6to4 Automatic Tunneling

If your network is an isolated IPv6 network that is not connected to an IPv6 ISP, you need to 
make sure that the IPv6 packets can travel over the IPv4 Internet backbone by enabling 
automatic 6to4 tunneling.

There are two requirements for 6to4 tunnelling:

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. A dynamic IPv4 
address can cause routing problems on the 6to4 tunnels.

If you do not use a stateful DHCPv6 server in your LAN:

 

Configure the Router Advertisement Daemon (RADVD), and set up 6to4 advertisement 
prefixes for 6to4 tunneling to function correctly. For information, see the “Configure the 
IPv6 Router Advertisement Daemon and Advertisement Prefixes for the LAN” section in 
Chapter 3, “LAN Configuration,” of the Reference Manual.

Typically, 6to4 tunnel addresses start with a 2002 prefix (decimal notification). On the 
wireless VPN firewall, a 6to4 tunnel is indicated by sit0-WAN1.

Select Network Configuration > WAN Settings > 6 to 4 Tunneling.

Select the Enable Automatic Tunneling check box.

Click Apply to save your changes.

Configure ISATAP Automatic Tunnelling

If your network is an IPv4 network or IPv6 network that consists of both IPv4 and IPv6 
devices, you need to make sure that the IPv6 packets can travel over the IPv4 intranet by 
enabling and configuring Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) 
tunneling.

If you do not use a stateful DHCPv6 server in your LAN:

 

Configure the Router Advertisement Daemon (RADVD), and set up ISATAP advertisement
