Firewall Policy Examples

Firebox Vclass User Guide

215

rized users are allowed to gain external access. Unautho-
rized users are still blocked.

1

Use the Account Manager to create end-user access
accounts for each individual to be allowed Internet
access during working hours.

2

Distribute login IDs, passwords, and connection
instructions to these users so that they can connect
through the firewall.

3

Create an “Allow_User” firewall policy using the
parameters shown below.

:

4

Add the “9to5M-F” schedule from Example 2 to this
policy so that it takes effect only between 9am and
5pm, Monday through Friday. This permits the
“Allow_HTTP” policy to be active outside the specified
office hours, at which time all users can surf the
Internet.

5

Before this group of authorized users can access the
Internet, they must first authenticate their access
request so that they can proceed through the firewall.
They would do so by entering the following URL in
their Web browser:

https://126.20.20.1/user.html

In this URL, the “126.20.20.1” entry represents the IP
address of interface 0.
