1.4.1.2 Ethernet WAN
If you prefer not to use a DSL line and you have another broadband modem or router (such as
ADSL) available, you can convert LAN port number four as a WAN port using the Network Setting
> Broadband > Ethernet WAN screen and then connect the LAN port to the broadband modem
or router. This way, you can access the Internet via an Ethernet connection and still use the QoS,
Firewall and parental control functions on the VMG.

1.4.2 VMG’s USB Support
The USB port of the VMG is used for 3G WAN backup, file-sharing and media server.
3G WAN Backup
Connect a 3G/LTE USB dongle with an active SIM card to the USB port. This adds a second WAN
interface and allows the VMG to wirelessly access the Internet via a 3G/LTE network. The 3G/LTE
WAN connection is the failover or a backup in case the DSL or Ethernet WAN connection fails.
To set up a 3G/LTE connection, click Network Setting > Broadband > 3G Backup.
To update the supported 3G/LTE USB dongle list, download the latest WWAN package from the
ZyXEL website and upload it to the VMG using the Maintenance > Firmware Upgrade screen.
See the product page on ZyXEL’s website for the list of 3G/LTE USB dongles that are compatible.
