Access Control
Use the Access Control tab to define a rule to block specific network devices within the network from
accessing certain services on the Internet. For example, you might prohibit one computer from surfing
the Web, another from transferring files using FTP, or the whole network from receiving incoming e-
mails.
Access controls work by placing restrictions on the types of requests that may pass from the network
out to the Internet and thus may block traffic flowing in both directions.
