Vigor 3300Bplus has 3 WAN interfaces, Vigor 3300 and Vigor 3300V both have 4 WAN interfaces. Below we will take Vigor 3300V for an example and introduce the settings for different types of Internet access, including Static, DHCP, PPPoE and PPTP. Also we will introduce the settings of Load Balance and Backup.
Please enter the Network – WAN page and click the Edit icon of WAN1.
Figure 15-1. The WAN setting of Network
Note: Vigor 3300B plus does not have WAN4. Only Vigor 3300V has VoIP function.

This line is Static, Downstream rate is 512k, and Upstream rate is 512k.
After the configuration, press the Apply button, then the router will automatically switch to the Network – WAN page.
Figure 15-3. The WAN1 (Static) setup
Now IP Mode is Static. If just one single WAN is used, please click Active and Default Route option. After clicking the Apply button, the router will enter the reboot page. Please wait about 70 seconds, and then the router will automatically switch to the System – Status page.
We will complete the settings for the left three WAN interfaces. The procedures are similar with the WAN1 setting. We will introduce the Load Balance and Backup functions based on these settings.

On the Network – WAN page, select Enable for Load Balance at first, then click the Auto Weight option. Now the pull-down menu of Weight is hidden with gray color. Activate the WAN (click Active) and add corresponding WAN interfaces to Load Balance. At last, you should select a WAN interface as VoIP usage (We recommend that you
consider the line which has fixed IP address, more upstream bandwidth or less traffic flow as your first choice, so that you can ensure the conversational quality of VoIP). Then please press the Apply button, the router will reboot after 70 seconds.
Figure 15-7. The WAN setting of network
Auto Weight uses the Downstream Rate/Upstream Rate set in WAN as primary number for assignment. The more bandwidth increases, the more proportion of usage. It is automatically assigned.
Note: The qualification of activating the traffic control and management for QoS also use the numbers of Downstream / Upstream Rate.
If you do not want to use Auto Weight, you must assign the proportion by yourself from the pull-down menu of Weight. The total percentage values must equal to 100%. Now the assignment is based on this manual setting, not the Downstream / Upstream Rate.
Figure 15-8. The weight equal to 100%
Click the Apply button and then the router will reboot for a while to switch to the
Figure 15-9. WAN status IP Address
It displays the WAN IP address.
RX(incoming) / TX(outgoing) Packets
You may calculate the traffic flow from the number of the packets (These numbers will not be cleared when the connection is dropped).
Connection Status
The status of Connected indicates that it is online, Disconnected indicates that it is offline. However, if the interface is set as Static mode, the status is always as Connected. Up Time
It shows the time period under Connected status (After Disconnected it will be reset to be 0).
Disconnect/Connect button
This button works only when IP Mode is PPPoE or PPTP. Users can manually drop and dial the connection.
Vigor 3300 has a detecting mechanism for WAN interface at regular intervals (by detecting the connection with gateway). If the WAN interface is offline, router will disconnect this line to ensure the normal function when Load Balance function is enabled (The packets will not be passed through the disconnected line).
Under offline status, Vigor 3300 always detects whether the WAN interface can be online again or not automatically and Vigor 3300 will connect the line again if detects
successfully. But this mechanism will not work after the line is manually dropped (Disconnect button), and work again until the line is manually connected again (Connect button).
Please refer to the table listed below.
WAN detecting mechanism
During online, auto detect if disconnected
After offline, auto detect if connected
Static/DHCP
Detect arp every 3 seconds.
Automatically disconnect if there is no response four times continuously.
During online, auto detect if disconnected
After offline, auto detect if connected
Automatically disconnect if there is no response two times continuously.
Automatically connect if receiving response.
Load Balance - Usage example
Suppose there are two PPPoE lines (charge per month) connected to WAN1 and WAN2 respectively. WAN1 has more Upstream bandwidth than WAN2. The proportion is set to 80% and 20%. The VoIP uses WAN2.
First of all, please configure the WAN1 and WAN2 interfaces (You may refer to the WAN configuration as an example), then Enable Load Balance. For the other settings please refer to the below figure. Press the Apply button to save the configuration and reboot the system.

For this feature you must firstly select Enable for Backup then please select Active and Backup-Master for the master line (Backup line's Active can not be selected, otherwise you cannot select Backup-Slave). Finally select Backup-Slave for the backup line. Click the Apply button to save this configuration, and then Vigor 3300 will take 70 seconds to reboot the system.
Figure 15-11. The setting of Backup
Enter the System – Status page after rebooting, and then click WAN Status, the Connection Status only WAN1 shows connected.
Figure 15-12. WAN1 status
WAN2 will not be automatically connected until WAN1 is disconnected. (Vigor 3300 still detect even WAN1 is offline.) And after WAN1 is connected again, WAN2 will be
Figure 15-13. WAN2 status Backup – Usage example
Suppose there are one Static IP line (charge per month) and the other PPPoE line (charge per minute/second) connected to WAN1 and WAN2 respectively. User wants to use WAN2 PPPoE line as backup. WAN2 will not be automatically connected until WAN1 is offline, and WAN2 will be automatically disconnected when the connection of WAN1 comes back.
First of all, please configure the WAN1 and WAN2 interfaces (You may refer to the WAN configuration as an example), then Enable the Backup function. For the other settings please refer to the below figure. Click the Apply button to save the configuration and reboot the system.
Note: When user enables Backup function, please always select WAN1 as the master interface.
Load Balance + Backup -Usage example
Suppose there are two PPPoE lines (charge per month) and a PPTP line(charge per minute/second) connected to WAN1, WAN2 and WAN3 respectively. Normally only WAN1 and WAN2 are used (Auto Weight). WAN3 won't be automatically connected until WAN2 is offline, and WAN3 will be automatically disconnected when the connection of WAN2 comes back. The VoIP uses WAN1.
First of all, please configure the WAN1, WAN2 and WAN3 (You may refer to the WAN configuration as an example), then Enable the Load Balance and Backup functions. For the other settings please refer to the below figure. Click the Apply button to save the configuration and reboot the system.
