IOS Question - Define inet-users

I am doing a security assessment of an organization that uses 871/881 routers with the firewall features enabled.  I see the following commands defining packet inspection done by the firewall software.

ip inspect name inet-users tcp

ip inspect name inet-users udp

ip inspect name inet-users icmp

What I am trying to define is the inspect name "inet-users".  It is obviously a constant defined by IOS as it is not defined anywhere in the configuration file like any other "variable" and does not generate an error.

What does "inet-users" define?  I'm assuming it is all users using the interface(s) where the inspect commands are used, but is that correct? 

The Cisco IOS manuals do not contain a reference to "inet-users" hence why I'm here asking.

Thank you.

Re: IOS Question - Define inet-users

"inet-users" is the name your the firewall-configuration. You can choose any name you want for this name. Mine are most often just named "FW" ... The name of the inspect-configuration is assigned to an interface to complete the firewall-config:

ip inspect name FW tcp

ip inspect name FW udp

ip inspect name FW icmp

ip inspect name FW ftp


interface dialer 0


ip inspect FW out

There is much more to configure for the firewall. You find many information on it by searching for the term CBAC (context based access control).
