Linksys BEFW11S4 User Manual

Filters block specific internal users from accessing the Internet. From the
Filters tab, as shown in Figure 5-14, you can set up a filter through an IP
address or a network port
number.
Setting Up Filters
To set up a filter using IP
addresses, enter the range
of IP addresses you wish
to filter in the IP address
fields. Users who have
filtered IP addresses will
not be able to access the
Internet at all. If you only
want to filter one IP
address instead of a range
of IP addresses, enter the
same value into both
fields. For instance, if you
wish to filter the PC with
the IP address of
192.168.1.5, enter 5 into
both fields on one line:
192.168.1.5 ~ 192.168.1.5.
Click the Apply button when you’re done.
To filter users by network port number, enter a network port number or a
range of network ports. Enter the port numbers you want to filter in the port
numbers fields. Users connected to the Router will no longer be able to
access any port number listed there.
Advanced Tab: Filters
Important: Filtering is an Advanced Function. No changes
should be made to this tab without a thorough understanding of
networking concepts.
