clients get IP addresses allocated from DTU with specific address range. The default LAN IP configuration
is as follows:
 LAN IP address/Gateway: 192.168.1.1
 Subnet mask: 255.255.255.0
To sets the LAN configuration parameters such as gateway IP, subnet mask and the enable DHCP flag,
along with DHCP parameters, please refer to clause “6.2.2DHCP”.
For Bridge mode, the Ethernet client device can get the WWAN interface IP directly via DHCP protocol.
