iptables Wrapper Script
To avoid creating conflicts between iptables and the nac-es service, do
not run the following commands manually:
■
/etc/init.d/iptables
■
service iptables start
■ service iptables stop
■
service iptables restart
The nac-es service must be shutdown before making changes to the ipta-
bles firewall. This script ensures that errors are not introduced by making
changes when nac-es is running.
Use the following commands to control iptables from the command line:
To stop iptables:
fw_control stop
To start iptables:
fw_control start
To restart iptables:
fw_control restart
To save iptables config:
fw_control save
To get iptables status (iptables -L):
fw_control status
Note that this last command can be used even if the nac-es service is running
since it makes no changes to the iptables rules.
