menu. If more than one scheduler rule is defined, the ‘Schedule’ drop-down menu will allow
you to choose between the available rules. To learn how to configure scheduler rules, refer

6. Click ‘OK’ to save the settings. You will be returned to the previous screen, while iPECS
SBG-1000 attempts to find the site. ‘Resolving...’ will appear in the ‘Status’ column while
the site is being located (the URL is ‘resolved’ into one or more IP addresses).
7. Click the ‘Refresh’ button to update the status if necessary. If the site is successfully
located, then ‘Resolved’ will appear in the status bar. Otherwise, ‘Hostname Resolution
Failed’ will appear. In case iPECS SBG-1000 fails to locate the website, perform the
following:
a. Use a web browser to verify that the website is available. If it is, then you probably
entered the website address incorrectly.
b. If the website is not available, return to the ‘Website Restrictions’ screen at a later time
and click the ‘Resolve Now’ button to verify that the website can be found and blocked
by iPECS SBG-1000.
You may edit the website restriction by modifying its entry under the ‘Local Host’ column in the
‘Website Restrictions’ screen.
• To modify an entry:
1. Click the action icon for the restriction. The ‘Restricted Website’ screen appears (see
Figure 5.25). Modify the website address, group or schedule as necessary.
2. Click the ‘OK’ button to save your changes and return to the ‘Website Restrictions’ screen.
• To ensure that all current IP addresses corresponding to the restricted websites are blocked,
click the ‘Resolve Now’ button. iPECS SBG-1000 will check each of the restricted website
addresses and ensure that all IP addresses at which this website can be found are included in
the IP addresses column.
You can disable a restriction in order to make a website available again without having to remove it
from the ‘Website Restrictions’ screen. This may be useful if you wish to make the website
available only temporarily, intending to block it again in the future.
• To temporarily disable a rule, clear the check box next to the service name.
• To reinstate it at a later time, simply reselect the check box.
• To remove a rule, click the service’s action icon. The service will be permanently removed.
