I have a development server with the lamp stack running CentOS:
[Prompt]# cat /etc/redhat-release
CentOS release 5.8 (Final)
[Prompt]# cat /proc/version
Linux version 2.6.18-308.16.1.el5xen ([email protected]) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-52)) #1 SMP Tue Oct 2 22:50:05 EDT 2012
[Prompt]# yum info iptables
Loaded plugins: fastestmirror

When I run:
service --status-all
Part of the output looks like this:
.... Snip....
httpd (pid xxxxx) is running...
Firewall is stopped.
Table: filter
Chain INPUT (policy DROP)
num target prot opt source destination
1 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0
Chain FORWARD (policy DROP)
num target prot opt source destination
1 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0
Chain OUTPUT (policy ACCEPT)
num target prot opt source destination
Chain RH-Firewall-1-INPUT (2 references)
....Snip....
iptables has been loaded to the kernel and is active as represented by the rules being displayed.
Checking just the iptables returns the rules just like status all does:
[Prompt]# service iptables status
Table: filter
Chain INPUT (policy DROP)
num target prot opt source destination
1 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0
Chain FORWARD (policy DROP)
num target prot opt source destination
1 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0
Chain OUTPUT (policy ACCEPT)
num target prot opt source destination
Chain RH-Firewall-1-INPUT (2 references)
.... Snip....
Starting or restarting iptables indicates that the iptables have been loaded to the kernel successfully:
[Prompt]# service iptables restart
Flushing firewall rules: [ OK ]
Setting chains to policy ACCEPT: filter [ OK ]
Unloading iptables modules: [ OK ]
Applying iptables firewall rules: [ OK ]
Loading additional iptables modules: ip_conntrack_netbios_n[ OK ]
[Prompt]# service iptables start
Flushing firewall rules: [ OK ]
Setting chains to policy ACCEPT: filter [ OK ]
Unloading iptables modules: [ OK ]
Applying iptables firewall rules: [ OK ]
Loading additional iptables modules: ip_conntrack_netbios_n[ OK ]
I've googled "Firewall is stopped." and read a number of iptables guides as well as the RHEL documentation, but no luck.
As far as I can tell, there isn't a "Firewall" service, so what is the line "Firewall is stopped."
referring to?
