Section 3.13:Firewall Configuration 43

Note

Do not use the numbers as seen in this sample configuration. These values

will not work for your own network configuration. If you are not sure what

values to enter, contact your network administrator for assistance.

If you have a fully qualified domain name for the network device, enter it in the Hostname field.

Tip

Even if your computer is not part of a network, you can enter a hostname

for your system. If you do not take this opportunity to enter in a name, your

system will be known as localhost.

Finally, enter the Gateway and Primary DNS (and if applicable the Secondary DNS and Ternary

DNS

) addresses.

3.13 Firewall Configuration

Red Hat Linux offers firewall protection for enhanced system security. A firewall exists between your

computer and the network, and determines which resources on your computer remote users on the

network can access. A properly configured firewall can greatly increase the security of your system.

Choose the appropriate security level for your system.
