What are some reasonable filtering rules for a Cisco?
The example in Figure 4 shows one possible configuration for using the Cisco as filtering router. It is a sample that shows the implementation of as specific policy. Your policy will undoubtedly vary.
In this example, a company has Class C network address 195.55.55.0. Company network is connected to Internet via IP Service Provider. Company policy is to allow everybody access to Internet services, so all outgoing connections are accepted. All incoming connections go through ``mailhost''. Mail and DNS are only incoming services.
