Configure the WAN options (optional)
. If required, change the factory default MTU size,
port speed, and MAC address of the wireless VPN firewall: see
Configure Advanced WAN
Options and Other Tasks
on page 47. These are advanced features, and you usually do not
need to change them.
Each of these four tasks is detailed separately in this chapter.
Tasks to Set Up an IPv6 Internet Connection to Your ISP
Complete these four tasks:
1.
Configure the IPv6 WAN mode
. Select the IPv4 / IPv6 mode to support both IPv4 and
IPv6 traffic: see
Configure the IPv6 Routing Mode
on page 36.
2.
Configure the IPv6 Internet connection to your ISP
. Connect to your ISP: see
Use a
DHCPv6 Server to Configure an IPv6 Internet Connection
on page 37 or
Configure a Static
IPv6 Internet Connection
on page 39. You can also program the WAN traffic meter if you
wish: see
Enable the WAN Traffic Meter
on page 335.
3.
Configure the IPv6 tunnels
. Enable 6to4 tunnels and configure ISATAP tunnels: see
Configure 6to4 Automatic Tunneling
on page 41 and
Configure ISATAP Automatic
Tunnelling
on page 42.
4.
Configure the WAN options (optional)
. If required, change the factory default MTU size,
port speed, and MAC address of the wireless VPN firewall: see
Configure Advanced WAN
Options and Other Tasks
on page 47. These are advanced features, and you usually do not
need to change them.
Each of these four tasks is detailed separately in this chapter.
Configure the IPv4 Internet Connection and WAN Settings
To set up your wireless VPN firewall for secure IPv4 Internet connections, you need to
determine the IPv4 WAN mode (see the next section) and then configure the IPv4 Internet
connection to your ISP on the WAN port. The web management interface offers two
connection configuration options, discussed in the following sections:
•
Let the Wireless VPN Firewall Automatically Detect and Configure an IPv4 Internet
Connection
on page 28
•
Manually Configure an IPv4 Internet Connection
on page 31
Configure the IPv4 WAN Mode
By default, IPv4 is supported and functions in NAT mode but can also function in classical
routing mode. IPv4 functions the same way in IPv4-only mode as it does in IPv4 / IPv6 mode.
The latter mode adds IPv6 functionality (see
Configure the IPv6 Routing Mode
on page 36).

Network Address Translation
Network Address Translation (NAT) allows all computers on your LAN to share a single public
Internet IP address. From the Internet, there is only a single device (the wireless VPN
firewall) and a single IP address. Computers on your LAN can use any private IP address
range, and these IP addresses are not visible from the Internet.
Note the following about NAT:
•
The wireless VPN firewall uses NAT to select the correct computer (on your LAN) to
receive any incoming data.
•
If you have only a single public Internet IP address, you need to use NAT (the default
setting).
•
If your ISP has provided you with multiple public IP addresses, you can use one address
as the primary shared address for Internet access by your computers, and you can map
incoming traffic on the other public IP addresses to specific computers on your LAN. This
one-to-one inbound mapping is configured using an inbound firewall rule.
Classical Routing
In classical routing mode, the wireless VPN firewall performs routing, but without NAT. To
gain Internet access, each computer on your LAN needs to have a valid static Internet IP
address.
If your ISP has allocated a number of static IP addresses to you, and you have assigned one
of these addresses to each computer, you can choose classical routing. Or, you can use
classical routing for routing private IP addresses within a campus environment.
To view the status of the WAN ports, you can view the Router Status screen (see
View the
System Status
on page 345).
Configure the IPv4 Routing Mode
To configure the IPv4 routing mode:
1.
Select
Network Configuration > WAN Settings
.
The WAN Mode screen displays:

Select the
NAT
radio button or the
Classical Routing
radio button.
WARNING:
Changing the WAN mode causes all LAN WAN and DMZ WAN
inbound rules to revert to default settings.
3.
Click
Apply
to save your settings.
Let the Wireless VPN Firewall Automatically Detect and
Configure an IPv4 Internet Connection
To automatically configure the WAN port for an IPv4 connection to the Internet:
1.
Select
Network Configuration > WAN Settings > Broadband ISP Settings
. In the
upper right of the screen, the IPv4 radio button is selected by default. The ISP
Broadband Settings screen displays the IPv4 settings:

Click the
Auto Detect
button at the bottom of the screen. The autodetect process probes
the WAN port for a range of connection methods and suggests one that your ISP is most
likely to support.
The autodetect process returns one of the following results:
•
If the autodetect process is successful, a status bar at the top of the screen displays
the results (for example,
DHCP service detected
).
•
If the autodetect process senses a connection method that requires input from you, it
prompts you for the information. The following table explains the settings that you
might have to enter:

•
If the autodetect process does not find a connection, you are prompted either to
check the physical connection between your wireless VPN firewall and the cable, DSL
line, or satellite or wireless Internet dish, or to check your wireless VPN firewall’s MAC
address. For more information, see
Configure Advanced WAN Options and Other
Tasks
on page 47 and
Troubleshoot the ISP Connection
on page 370.

To verify the connection, click the
Broadband Status
option arrow in the upper right of the
screen to display the Connection Status pop-up screen. (The following figure shows a static
IP address configuration.)
