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.

Configure the WAN options (optional)

. If required, change the factory default MTU size,

port speed, and MAC address of the wireless VPN firewall: see

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:

Internet and Broadband Settings

2.

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.

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:

Internet and Broadband 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:

Internet and Broadband Settings

•

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.)
