We have a requirement to setup Site-to-Site vpn between our Checkpoint FW and customer Palo Alto FW. I have created one, but the issue is IKE phase 2 fails. I have confirmed the negotiation parameters with my customer engineer and it looks like everything is in order. What could be the possible issue?
I used VPN tu and SmartView monitor to view but to no success. Any advices will be highly appreciated
Thank you so much
