Stateful Packet Inspection
Unlike simple Internet sharing routers, a firewall uses a process called stateful packet inspection to 
ensure secure firewall filtering to protect your network from attacks and intrusions. Since 
user-level applications such as FTP and web browsers can create complex patterns of network 
traffic, it is necessary for the firewall to analyze groups of network...

Inside Twisted Pair Cables
For two devices to communicate, the transmitter of each device must be connected to the receiver 
of the other device. The crossover function is usually implemented internally as part of the 
circuitry in the device. Computers and workstation adapter cards are usually media-dependent 
interface ports, called MDI or uplink ports. Most repeaters and switch ports...

Note: Flat “silver satin” telephone cable may have the same RJ-45 plug. However, using telephone 
cable results in excessive collisions, causing the attached port to be partitioned or disconnected 
from the network.

The WGR614 v4 router incorporates Auto UplinkTM technology (also called MDI/MDIX). Each 
LOCAL Ethernet port will automatically sense whether the Ethernet cable plugged into the port 
should have a normal connection (e.g. connecting to a PC) or an uplink connection (e.g. 
connecting to a router, switch, or hub). That port will then configure itself to the correct 
configuration. This...

December 2003
In your IP network, each PC and the firewall must be assigned a unique IP addresses. Each PC 
must also have certain other IP configuration information such as a subnet mask (netmask), a 
domain name server (DNS) address, and a default gateway address. In most cases, you should 
install TCP/IP so that the PC obtains its specific network configuration information automatically 
from a DHCP server during...
