McAfee Firewall Configurations
8. Choose File/Save Settings if you want to write this new configuration to
disk immediately. Note: the configuration is automatically written to disk
when you exit McAfee Firewall.
Configuring System Settings
The following steps will help the Administrator set up the System portion of
the configuration. While the configuration file (CPD.SFR) is not intended to be
transferrable, the Applications settings can be successfully copied from one
system to another. The System settings cannot. This is because different
systems have different network devices and it is uncommon to find two that
are the same.
1. List all the network segments that are connected to computers that are to
be configured.
Include internal networks and any connection to an external network (e.g.
the Internet) even if it is by modem. This is often a simple task, since most
computers have just one or two network connections.
2. Decide what network traffic should be allowed on each network segment.
3. Select the Settings menu item, and the System option on the popup menu.
4. From the list of network devices, determine which device is connected to
which network segment you listed in Step (1). If you have one modem but
see two "Dial-Up Adapter" entries, one of them may be a Microsoft Virtual
Private Network Adapter. Usually, the entry with the lower device number
(e.g. [0000]) is the physical device and the other is the virtual device.
5. For each device:
• Highlight the device in the list and select Properties.
• According to the policies you defined in Step (2) above, allow or block
the different types of network traffic.
• Choose OK when done. Note: changes take effect for this device when
you choose OK on the Properties page. Choosing Cancel on the
System/Settings page does not cancel these changes. If in doubt, review
the settings later to confirm.
6. Choose OK to close the System/Settings dialog box.
NOTE: You must check System Settings after adding or removing
network devices.
