Questions about CBAC

Hi *,

How to place correctly the command 'ip inspect NAME in|out' ?

Example :

Inside_Network

fa0/0 CBAC fa0/1

Outside_Network

From the Cisco website, I can find : 'ip inspect NAME in' on fa0/0
Context-Based Access Control (CBAC): Introduction and Configuration [Cisco IOS Firewall] - Cisco Systems

From the Packetlife website, I can find: 'ip inspect NAME out' on fa0/1
IOS Context-Based Access Control (CBAC) - Packet Life

I'm confusing, what's the best choice ?

Thanks a lot,

Think of it as if you were creating basic standard access-list do you want to apply the settings for the packets going inbound or outbound.

you can try this command

ip inspect name FWOUT tcp
ip inspect name FWOUT udp
ip inspect name FWOUT icmp
ip inspect name FWOUT ftp

//ftp is important to inspect because it can use a secondary port initiated from the outside

ip access-list extended INBOUND
deny ip any any

int fa0/0
description OUTSIDE
ip access-group INBOUND in
ip inpsect FWOUT out
ip address 1.1.1.1 255.255.255.0
ip nat outside

int fa0/1
description INSIDE
ip address 192.168.0.1 255.255.255.0
ip nat inside

^^ THIS is the generally accepted way of doing it. If you are inspecting on the inside you need a specific reason to do so.
