CHAPTER 14 RULES AND FILTERS

There are four basic types of rules:

1IP filter rules,

2Radius rules (actually a combination of previously defined IP filter rules),

3traffic control rules, and

4transparent bridge rules (similar to IP filter rules, but for applications that use a transparent bridge).

IP filter rules and traffic control rules will be covered in detail in this chapter. See section 4.7 of the CyROS Reference Guide for more information about all four types of rules.

As an introduction, the Rules List Menu Tree is presented in Figure 12.1. First, a rule list is created and named. Second, rules are added to the list and defined.

Configuration of IP Filters

IP Filter rules are a very important part of a network’s firewall. They permit packets into or out of the network depending on the source and destination IP addresses, the source and destination ports, the protocol used, and the ACK bit for TCP packets. The Syslog can be used to monitor the packets that meet the rules applied in this menu.
