3.2 Network Setup

For Internet access, it is necessary for you to set WAN and LAN interfaces for the router.

3.2.1 WAN and Internet Access Setup

The Vigor3300 Series supports four WAN interfaces (Static, DHCP, PPPoE and PPTP), which share the same setting page. In the Network group, please click the WAN option. The following page will be shown.

Note: Vigor3300/3300V supports four WAN interfaces, yet Vigor3300B+ supports three WAN interfaces. That is, #WAN4 will be disabled for Vigor3300B+.

Load Balance	Enables or disables the WAN load balance function. The Auto Weight
	option becomes available if Enable mode is selected. Load Balance
	allows the router distributing data in and out of the Internet by using
	different WAN interfaces at the same time.
Backup	Enables or disables backup function for WAN interfaces. If you enable
	this function, the backup-master/backup-slave will execute the job of
	master/slave device when the master/slave device fails to work.
