Configuring the Firewall 

47

Firewall 
Configuration

To configure the firewall, you can define up to 10 "rules" using the 

Firewall 

Configuration

 screen on the User Interface in the DW4020. If the control 

information in an incoming packet matches 

any

 of the defined rules, the 

DW4020 

drops

 the packet. So a packet will be passed from the Internet through 

the DW4020 to the LAN, and thus to your computers, only if the packet doesn't 
match any of the rules that you have defined. If you haven't defined any rules, all 
packets will be passed through the firewall.

Configuring rules

Note that the rules that you configure apply to all traffic bound for 

any

 of your 

LAN computers. This means that you can't block certain kinds of traffic (for 
example, a "ping" from another computer trying to see if it can establish a 
connection) from reaching some of your computers without blocking that kind 
of traffic to all of your computers. To configure the firewall, follow the steps 
below.

1. Access the 

User Interface

 and click on 

Firewall Configuration

. The screen 

in Figure 44 appears.

2. Check the 

Enable Firewall 

box. 

The firewall starts (as shown in the figure) with no rules defined. Each rule 
requires that you specify four fields. If the DW4020 firewall is enabled it 
will check the fields specified in each IP packet that comes in from the 
Internet bound for your LAN to see if they match any of the rules that you 
have defined. If there is a match for all fields with any of the rules that you 
have defined, the firewall won't deliver the packet to the LAN. The fields to 
be specified for each rule definition are:
