Use the same VLAN ID on different WANs (For Vigor3900/2960)

By default, Vigor3900, Vigor2960 and Vigor300B do not allow the same VLAN ID configuration for different WANs. To use the one VLAN ID on more WAN interfaces, we have to change Switch Mode from "Normal" to "Double Tag" first. Below is an example of configuring WAN2 to have the same VLAN ID as WAN1.

1. Go to WAN >> General Setup and then select "Double Tag" for Switch Mode.

2. On the same page, double click on wan2 profile and then configure the same VLAN ID as wan1. The configuration can be applied now.

Note: Vigor3900 with hardware version 1 doesn't support Double Tag feature due to the limitations of the switch.
