The lan interface is in factory default state configured as an interface offering a DHCP server on the br-lan network device. br-lan is in fact a virtual bridge switching between the hardware interfaces eth0 and eth1, which represent the hardware ethernet interfaces of the MC-MR-L2. 10.1 Cellular connection setup A mobile WAN interface configuration is present in factory default state, which should only require small provider-dependent adjustments to establish a mobile broadband connection. - Page 15 Switch to the Firewall Settings tab to ensure the mobile interface is added to the wan firewall zone. After clicking SAVE & APPLY, it is recommended to reboot or briefly disconnect the router to ensure the modem is properly reinitialized.
