ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N

Isolated IPv6 network. 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; you do this by enabling automatic 6to4 tunneling (see Configure 6to4 Automatic Tunneling on page 46).

Mixed network with IPv4 and IPv6 devices. If your network is an IPv4 network that consists of both IPv4 and IPv6 devices, you need to make sure that the IPv6 packets can travel over the IPv4 intranet; you do this by enabling and configuring ISATAP tunneling (see Configure ISATAP Automatic Tunneling on page 47).

Note: A network can be both an isolated IPv6 network and a mixed network with IPv4 and IPv6 devices.

After you have configured the IPv6 routing mode (see the next section), you need to configure the WAN port with a global unicast address to enable secure IPv6 Internet connections on your wireless VPN firewall. A global unicast address is a public and routable IPv6 WAN address that can be statically or dynamically assigned. The web management interface offers two connection configuration options:

Automatic configuration of the network connection (see Use a DHCPv6 Server to Configure an IPv6 Internet Connection on page 39)

Manual configuration of the network connection (see Configure a Static IPv6 Internet Connection on page 41 or Configure a PPPoE IPv6 Internet Connection on page 43)

Configure the IPv6 Routing Mode

By default, the wireless VPN firewall supports IPv4 only. To use IPv6, you need to enable the wireless VPN firewall to support both devices with IPv4 addresses and devices with IPv6 addresses. The routing mode does not include an IPv6-only option; however, you can still configure a native IPv6 network if your ISP supports IPv6. These are the options:

IPv4-only mode. The wireless VPN firewall communicates only with devices that have IPv4 addresses.

IPv4/IPv6 mode. The wireless VPN firewall communicates with both devices that have IPv4 addresses and devices that have IPv6 addresses.

Note: IPv6 always functions in classical routing mode between the WAN interface and the LAN interfaces; NAT does not apply to IPv6.

To configure the IPv6 routing mode:

1. Select Network Configuration > WAN Settings. The WAN Mode screen displays:

IPv4 and IPv6 Internet and Broadband Settings
