4G PoE IIoT Gateway
The purpose is to shorten the switch time during failover process. So, when primary connection is
disconnected, failover interface will take over the data transfer mission instantly by only changing routing
path to the failover interface. The dialing-up time of failover connection is saved since it has been
connected beforehand.
VLAN Tagging
Sometimes, your ISP required a VLAN tag to be inserted into the WAN packets from Gateway for specific
services. Please enable VLAN tagging and specify tag in the WAN physical interface. Please be noted that only
Ethernet and ADSL physical interfaces support the feature. For the device with 3G/4G WAN only, it is disabled.
