6.1.2.1 About LAN
IP Address
Similar to the way houses on a street share a common street name, so too do computers on a LAN share
one common network number. This is known as an Internet Protocol address.
Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your LTE7460-M608 will compute
the subnet mask automatically based on the IP address that you entered. You don't need to change
the subnet mask computed by the LTE7460-M608 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 LTE7460-M608 has a built-in DHCP server capability that assigns IP addresses and DNS
servers to systems that support DHCP client capability.
6.1.2.2 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 LTE7460-M608 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.
