Internet and WAN Configuration Tasks
The tasks that are required to complete the Internet connection of your wireless VPN firewall
depend on whether you use an IPv4 connection or an IPv6 connection to your Internet
service provider (ISP).
Note: The wireless VPN firewall supports simultaneous IPv4 and IPv6
connections.

Tasks to Set Up an IPv4 Internet Connection to Your ISP

Complete these four tasks:
1. Configure the IPv4 WAN mode. Select either NAT or classical routing: see Configure
the IPv4 WAN Mode on page 26.
2. Configure the IPv4 Internet connection to your ISP. Connect to your ISP: see Let the
Wireless VPN Firewall Automatically Detect and Configure an IPv4 Internet Connection on
page 28 or Manually Configure an IPv4 Internet Connection on page 31. You can also
program the WAN traffic meter if you wish: see Enable the WAN Traffic Meter on page 335.
3. Configure Dynamic DNS on the WAN port (optional). If required, configure your fully
qualified domain names: see Configure Dynamic DNS on page 45.
