Policy (Firewall) Configuration
Some Examples
Your DFL-600 allows you to make policy rules and then group these rules
into a policy that will limit the types of access PCs on your LAN can have to
the WAN (Internet). In addition, you can create a Schedule that will
determine at what times and days of the week these policies are enforced.
Finally, the DFL-600 offers a Global Policy Status page that allows you to
enable or disable the filters that control what type of access to the WAN
(Internet) PCs on your LAN can have, and what type of access to Virtual
Servers and Application (ALGs) on your LAN can be granted to PCs on the
WAN (Internet).
The DFL-600 offers many preset options for making these policies, and
rather than describing them individually, a series of examples may be most
informative.
Example 1 − Limiting Web-page Access
In this example, you will deny any PC on your LAN from accessing web-
pages on the WAN (Internet) between the hours of 6 pm and 9 pm, Monday
through Friday.
Setting the Schedule
Let's say that you are concerned that your children will access web-pages on
the Internet when they should be studying or doing their homework. In this
case, the schedule would be established first. To do this, click on the
Schedule button to open the Schedule Rules page, as shown below.
