Hands-On Project 9-4: Designing a Rule Base

Objective: Create a basic rule base for packet filtering.
Description: In this activity, you configure a set of basic packet-filtering rules for a network. The internal network is represented by 192.168.120.0; the firewall is hosted at 192.168.120.1; the e-mail server is at 192.168.120.2; the Web server is at 192.168.120.3; and the DNS server is at 192.168.120.4. Design the rule base using Table 9-13 to accomplish the following goals:

1. Create a rule that allows internal hosts to access the external network.

2. Create a rule that prevents access to the firewall.

3. Create a rule that allows internal and external access to the e-mail server and Web server.

4. Create a rule that allows internal access to the DNS server.
