This recipe describes how to configure the WAN interface via the console instead of through the web GUI. Note that the options are much more limited than they are in the web GUI. For example, you only have the option to configure an IPv4 address via DHCP or use a static address. None of the other options, such as PPP or PPPoE are available. Also, with IPv6, the only option is DHCP6. If you require more options that are available here, use the web GUI.
