3.4.3.3.6 Configuring Website Restrictions
You can configure the device to block specific Internet web sites so that they cannot be
accessed from computers in the home network. Moreover, restrictions can be applied to a
comprehensive and automatically-updated table of sites to which access is not
recommended.
¾
To block access to a web site:
1. Click the Web Restrictions item ( Configuration tab > Data Settings menu >
Firewall submenu > Web Restrictions page item); the following page appears:
Figure 3-60: Configuring Website Restrictions
2. Click the New Entry link; the following page appears:
Figure 3-61: Adding a Restricted Website
3. In the 'Restricted Website' field, enter the URL (or part of the URL) that you want to
make inaccessible from your home network (all Web pages within this URL are also be
blocked). If the URL has multiple IP addresses, the device resolves all additional
addresses and automatically adds them to the restrictions table.
4. From the 'Local Host' drop-down list, specify the computer or group of computers to
which you want to apply the Web site restriction. Select an address or a name from the
list to apply the rule on the corresponding host, or 'Any' to apply the rule on all the
device's LAN hosts. If you want to add a new address, select the 'User Defined' option
and add a new Network Object representing the new host (refer to ''Configuring
Network Objects'' on page
121 ).
5. From the 'Schedule' drop-down list, select the time during which the rule is active. By
default, the rule is always active. However, you can configure scheduler rules by
selecting 'User Defined', and then defining the day and time period during which the
rule is active. Once a scheduler rule(s) is defined, the 'Schedule' drop-down list allows
you to choose an available rule (for defining user-defined schedule rules, refer to
''Configuring Scheduler Rules'' on page
122 ).
6. Click OK to save the settings; you are returned to the previous page while the device
attempts to find the site. 'Resolving...' appears in the Status column while the site is
being located (the URL is 'resolved' into one or more IP addresses).
7. Click Refresh to update the status if necessary. If the site is successfully located, then
'Resolved' appears in the status bar, otherwise 'Hostname Resolution Failed' appears.
