Filtering Policies

You can select one of the two filtering policies:

•

Allow all to pass except those that match the specified rules

•

Deny all to pass except those that match the specified rules

Filtering Rules

You can specify eight rules for each direction: inbound or outbound. For each rule,

you can define the following:

•

Source IP address

•

Destination IP address

•

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.

The URL Blocking Page

You can use the

page to block LAN computers from connecting to

pre-defined Web sites. 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.
