User Guide
don't need to change the subnet mask computed by the LTE Device unless you are instructed
to do otherwise.
DHCP
DHCP (Dynamic Host Configuration Protocol) allows clients to obtain TCP/IP configuration
at start-up from a server. This LTE Device has a built-in DHCP server capability that assigns
IP addresses and DNS servers to systems that support DHCP client capability.
DNS
DNS (Domain Name System) maps a domain name to its corresponding IP address and vice
versa. The DNS server is extremely important because without it, you must know the IP
address of a computer before you can access it. The DNS server addresses you enter when
you set up DHCP are passed to the client machines along with the assigned IP address and
subnet mask.

6.1.1.2 About UPnP

How do I know if I'm using UPnP?
UPnP hardware is identified as an icon in the Network Connections folder (Windows XP).
Each UPnP compatible device installed on your network will appear as a separate icon.
Selecting the icon of a UPnP device will allow you to access the information and properties of
that device.
Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and
opening firewall ports may present network security issues. Network information and
configuration may also be obtained and modified by users in some network environments.
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the LTE Device allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional
configuration. Disable UPnP if this is not your intention.
