Configuring a Simple  Firewall The Cisco 1800 integrated services routers support network traffic filtering by means of access lists. The router also supports packet inspection and dynamic temporary access lists by means of Context-Based Access Control (CBAC). Basic traffic filtering is limited to configured access list implementations that examine packets at the network layer or, at most, the transport layer, permitting or denying the passage of each packet through the firewall. However, the use of inspection rules in CBAC allows the creation and use of dynamic temporary access lists. These dynamic lists allow temporary openings in the configured access lists at firewall interfaces. These openings are created when traffic for a specified user session exits the internal network through the firewall. The openings allow returning traffic for the specified session (that would normally be blocked) back through the firewall. . 8-1 Router with Firewall Configured 1.
