6.8 Technical Reference
This section provides some technical background information about the topics covered in this
chapter.
LANs, WANs and the LTE Device
The actual physical connection determines whether the LTE Device ports are LAN or WAN ports.
There are two separate IP networks, one inside the LAN network and the other outside the WAN
network as shown next.

LAN and WAN IP Addresses
DHCP Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to
obtain TCP/IP configuration at start-up from a server. You can configure the LTE Device as a DHCP
server or disable it. When configured as a server, the LTE Device provides the TCP/IP configuration
for the clients. If you turn DHCP service off, you must have another DHCP server on your LAN, or
else the computer must be manually configured.
IP Pool Setup
The LTE Device is pre-configured with a pool of IP addresses for the DHCP clients (DHCP Pool). See
the product specifications in the appendices. Do not assign static IP addresses from the DHCP pool
to your LAN computers.
