Configuration Guide

6
a) NAT Mode, the ODU work as a LTE and Ethernet Gateway, it converts LTE network data to local
Ethernet data.
b) Tunnel Mode, the ODU can build a L2 or L3 VPN tunnel with a designated VPN server.
c) Bridge Mode, the ODU can bridge it LTE IP address to LAN port devices, when configured as the
bridge, the CPE’s LAN port will work as trunk mode, so it can’t assign IP address to any no-trunk
devices (like PC), so you have to Manual Configure the PC’s IP address in the same broadcast
domain (e.g. 192.168.150.88).
(2) IDU+ODU Mode
When the ODU connect to a IDU device (Baicells PoE router), it will automatic be configured as Bridge
mode, and assign all its LTE IP to IDU, at that mode, the IDU will take the place of ODU to control all the CPE
functions.
CAUTION:
Before contacting Baicells FAE or your distributor, please DO NOT mixed use the two
modes.
