If you are using
iptables, you will need to synchronize the appropriate configuration file on the backup LVS router.
If you alter the any network packet filter rules, enter the following command as root from the primary LVS router:
scp /etc/sysconfig/iptables n.n.n.n:/etc/sysconfig/
In the command, replace n.n.n.n with the real IP address of the backup LVS router.
Next either open an
ssh session to the backup router or log into the machine as root and type the following command:
/sbin/service iptables restart
