Manually deleting IPsec VPN load balancing flow rules

Previous versions of FortiOS for FortiGate-6000 and 7000 used load balancing flow rules to handle IPsec VPN traffic. The default versions of these flow rules sent all IPv4 and IPv6 IPsec VPN traffic to the primary (master) FPC or FPM. Enabling IPsec VPN load balancing by enabling the ipsec-load-balance option of the config load-balance settings command enabled these flow rules. Disabling IPsec VPN load balancing disabled them.

For FortiOS 6.0.6, you no longer need these flow rules and they should be manually removed after upgrading to FortiOS 6.0.6. Upgrading to FortiOS 6.0.6 does not automatically remove them. For more information, see FortiGate-6000 IPsec VPN load balancing support and FortiGate-7000 IPsec VPN load balancing changes .

Example IPv4 and IPv6 IPsec VPN flow rules that can be removed after upgrading to FortiOS 6.0.6:
