Hi Guys,<br />
<br />
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 &nbsp;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

Internet is not accessible

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
