travel over the IPv4 intranet; you do this by enabling and configuring ISATAP tunneling
(see
Configure ISATAP Automatic Tunnelling
on page 42).
Note:
A network can be both and 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 37)
•
Manual configuration of the network connection (see
Configure a Static IPv6 Internet
Connection
on page 39)
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 still can
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:

Select the
IPv4 / IPv6 mode
radio button. By default, the IPv4 only mode radio button is
selected, and IPv6 is disabled.
WARNING:
Changing the IP routing mode causes the wireless VPN firewall to
reboot.

Use a DHCPv6 Server to Configure an IPv6 Internet
Connection
The wireless VPN firewall can autoconfigure its ISP settings through a DHCPv6 server by
using either stateless or stateful address autoconfiguration:
•
Stateless address autoconfiguration
. The wireless VPN firewall generates its own IP
address by using a combination of locally available information and router
advertisements, but receives DNS server information from a DHCPv6 server.
Router advertisements include a prefix that identifies the subnet that is associated with
the WAN port. The IP address is formed by combining this prefix and the MAC address of
the WAN port. The IP address is a dynamic address.
•
Stateful address autoconfiguration
. The wireless VPN firewall obtains an interface
address, configuration information such as DNS server information, and other
parameters from a DHCPv6 server. The IP address is a dynamic address.

To automatically configure the WAN port for an IPv6 connection to the Internet:
1.
Select
Network Configuration > WAN Settings > Broadband ISP Settings
.
2.
In the upper right of the screen, select the
IPv6
radio button. The ISP Broadband Settings
screen displays the IPv6 settings:
Figure 17.
3.
In the Internet Address section of the screen, from the IPv6 drop-down list, select
DHCPv6
.
4.
In the DHCPv6 section of the screen, select one of the following radio buttons:
•
Stateless Address Auto Configuration
.
•
Stateful Address Auto Configuration
.
5.
As an optional step: If you have selected the Stateless Address Auto Configuration radio
button, you can select the Prefix Delegation check box:
•
Prefix delegation check box is selected
. A prefix is assigned by the ISP’s
stateful
DHCPv6 server through prefix delegation. For example, 2001:db8:: /64. The wireless
VPN firewall’s
stateless
DHCPv6 server can assign this prefix to its IPv6 LAN clients.
For more information about prefix delegation, see
Stateless DHCPv6 Server With
Prefix Delegation
on page 71.
•
Prefix delegation check box is cleared
. Prefix delegation is disabled. This is the
default setting.

To verify the connection, click the
Status
option arrow in the upper right of the screen to
display the Connection Status pop-up screen. (The following figure shows a dynamic IP
address configuration.)
Figure 18.
The Connection Status screen should show a valid IP address and gateway, and you are
connected to the Internet. If the configuration was not successful, see
Troubleshoot the
ISP Connection
on page 370.
Note:
For more information about the Connection Status screen, see
View
the WAN Port Status
on page 356.
Configure a Static IPv6 Internet Connection
To configure a static IPv6 Internet connection, you need to enter the IPv6 address information
that you should have received from your ISP.
To configure static IPv6 broadband ISP settings:
1.
Select
Network Configuration > WAN Settings > Broadband ISP Settings
.
2.
In the upper right of the screen, select the
IPv6
radio button. The ISP Broadband Settings
screen displays the IPv6 settings:
