Understanding Your Firewall

Your Wireless-G Router Model WGR614v10 contains a true firewall to protect your network from

attacks and intrusions. A firewall is a device that protects one network from another while

allowing communication between the two. Using a process called Stateful Packet Inspection, the

firewall analyzes all inbound and outbound traffic to determine whether or not it will be allowed to

pass through.

By default, the firewall allows any outbound traffic and prohibits any inbound traffic except for

responses to your outbound traffic. However, you can modify the firewall’s rules to achieve the

following behavior:

• Blocking sites. Block access from your network to certain Web locations based on Web

addresses and Web address keywords. This feature is described in “Blocking Access to

Internet Sites” on page 3-1.

• Blocking services. Block the use of certain Internet services by specific computers on your

network. This feature is described in “Blocking Access to Internet Services” on page 3-3.

• Scheduled blocking. Block sites and services according to a daily schedule. This feature is

described in “Scheduling Blocking” on page 3-5.

• Allow inbound access to your server. To allow inbound access to resources on your local

network (for example, a Web server or remote desktop program), you can open the needed

services by configuring port forwarding as described in “Allowing Inbound Connections to

Your Network” on page 5-1.

• Allow certain games and applications to function correctly. Some games and applications

need to allow additional inbound traffic in order to function. Port triggering can dynamically

allow additional service connections, as described in “Allowing Inbound Connections to Your

Network” on page 5-1. Another feature to solve application conflicts with the firewall is

Universal Plug and Play (UPnP), described in “Using Universal Plug and Play” on page 5-12.
