For some days it is bottering me that my IPsec tunnel keeps rebuilding (Make-before-break) every 1-4 minutes.

What can cause this? My pfsense box is connected via IPsec to a checkpoint firewall R80.3

Here is the log from the pfsense side, if needed I also can retrieve some information from the Checkpoint firewall but it will be very basic as we do not have the monitoring blade enabled.

Remote side: 123.123.123.123
My side: 66.66.66.66

Can somebody explain to me what is happening here? If more information is needed from the remote side please let me know. I need to retrieve the information then but it can take a while before I have it.

Every help is really appreciated!

Thanks,
