IOS Firewall
When your router is running IOS image with FW feature, you can implement CBAC as a Stateful Firewall IOS-based. With such inspection, the router can inspect inbound traffic from outside such as The Internet to inside the network. The router can also inspect outbound traffic from inside the network to outside. Note that the sample configurations implement outbound inspection on the WAN (Internet) interface that regulate outbound traffic from inside to the Internet.
Typically no inspection is necessary or even needed to regulate traffic between inside or non-Internet interfaces. When there are no public servers hanging off the router and there are only outbound traffic such as Internet browsing (in addition of no inspection between inside interfaces), there should be no reason to implement inspection on inside interface. Therefore it is common practice to implement inspection on the WAN (Internet) interface to regulate outbound traffic when there are multiple non-Internet interfaces on the router and/or there are no inbound traffic.
