Hi Guys,

In our network we have used Checkpoint UTM-1 firewall at perimiter level. Last sunday due to power cable issue failover occurs and users were complained that internet was not working for them. When Firewall 1 came up internet was working fine. Yesterday night for testing purpose we reboot the firewall 1  and suddenly internet went down we could not able to access any site. Software version 75.20. Both firewall are High Availability and 70:30 ratio. I have started my career few months back. Please help me resolve this issue
