Query : We are running a pair of Check Point Firewall with ClusterXL in active-active mode. We want to achieve zero downtime when rebooting 1 Checkpoint Firewall which is active as the pair of firewalls is supporting 24 x7 service which we cannot afford downtime during rebooting of firewalls. The consideration is the packets-in-transit passing through the Checkpoint firewall during the reboot.
How to ensure these packets-in-transit has flowed through this particular firewall gracefully and no new packets come in to this firewall before the firewall is reboot?
Version: R80.10
Thanks in Advance.
