Destination Port
Use Rule#
For the
Source
or
Destination IP address
, you can define a single IP address
(4.3.2.1). An empty field implies any IP address.
For
Destination Port
, you can define a single port (80) or a range of ports
(1000-1999). No prefix indicates both TCP and UDP are defined. Leaving this empty
implies that all port addresses apply.
Each
Rule
can be enabled or disabled individually.
You can use packet filters with scheduling rules for more access control flexibility.
The Domain Filters Page
You can use the
Domain Filters
page to enable or deny user access to specified
URLs. Domain filtering and URL Blocking perform similar functions. The major
difference between Domain Filtering and URL Blocking is that Domain Filtering
requires the user to input a suffix whereas URL Blocking requires the user to input a
keyword only. In other words, Domain Filtering can block a specific web site, whereas
URL Blocking can block hundreds of web sites by specifying a keyword.
Domain Filter
Use to prevent users behind this device from accessing specific URLs.
Log attempted URL Access
Check if you want to log the action when someone accesses the specific
URLs.
Privilege IP Address Range

Domain Suffix
The suffix of the restricted URL; for example,
xxx .com
.
Action
The action to be taken when a user accesses the restricted domain suffix
URL. Check

to block access. Check
log
to record the attempted
access.
