The next step, once the Teldat 4Ge has a valid IP address, is to set the data backup mechanism.
The latter is performed by VLAN 463. Through this VLAN, the Teldat 4Ge assigns the public IP it has obtained to the
router's Ethernet subinterface belonging to the same VLAN and sets a new default route to redirect traffic to the 4G
network.
