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.

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).
