You can change the times and days entered for a Schedule by clicking on the

page for the corresponding Schedule Name, and allow you to make changes.
Setting the Policy Rules
Now you need to configure the DFL-600 to block PCs on your LAN from
accessing Web-pages on the WAN (Internet). To do this, click on the Policy
button to open the Policy Rules page, as shown below.
Enter a name for this rule in the Rule Name field. This name is used to
reference the Policy Rule. For this example, we will use BlockWeb for the
policy rule name.
In order to block PCs on your LAN from downloading web-pages from the
WAN (Internet), you need to select the HTTP (Hyper Text Transfer Protocol)
from the Protocol drop-down menu. HTTP is the protocol that the World
Wide Web uses to transfer web pages from the Internet to a PC on your LAN.
The HTTP protocol uses TCP port 80 to make connections to PCs, but the
necessary parameters for a Policy Rule are already entered when you select
http(80) from the Protocol drop-down menu.
Most of the commonly used protocols on the Internet are already entered in
the Protocol drop-down menu.
Next you need to specify the IP addresses of the possible sources of PCs on
your LAN that this Policy Rule will apply to. You can specify any IP address
range that may include all of the PCs on your LAN, or limit the IP address
