Hi Pranav, Thanks for your reply.
Actually i am working in GajShield Infotech. We have already developed firewall. In our Firewall there is one option HA. For HA we are using keepalived. I am not having much idea about working of HA. I have to do some modification in existing configuration of HA. That's why i would like to know is the exact working of HA. Can you provide me any documentation on HA with keepalived of heartbeat and drbd? Thanks, Ameet Tirodkar.
