Modem Router Mode
In Modem router mode, and when the ETM350C/450C has an IP address, the ETM350C/450C
shares the allocated IP with any connected Host devices via NAT. In this mode the
ETM350C/450C acquires its IP from the mobile network and the device connected to the
ETM350C/450C has a private IP allocated via DHCP from the ETM350C/450C.
There are two options for operation in Modem Router Mode, Always On-line and Demand On-line
under Manual mode. For setting these options, refer to the [WAN] settings section
