Site to Site VPN Key Install

[bdawg1616_]

We are trying to establish a Site to Site VPN.  CheckPoint on our Side to Palo Firewall on Vendor Side. 

Vendor Palo Firewall is in passive mode 

The traffic is always initiated from behind the check point Fw . 

Currently we have some test traffic being successful going over the VPN. So traffic is working. 

When we are looking in the logs  on the firewall . 

The Key install log starts up around every 45 minutes 

The Checkpoint starts we show this log message: Child SA exchange: Created a child SA successfully

The Vendor responds Show this log message from the Vendor:  Informational exchange: Received delete IPsec SA request for: 0x

This happens 4 times.  normally ending with the Vendor response being the last log message.
