Quantum Spark IPsec Tunnel Issue with Loopback Interface

[khineminn]

According to our customer requirement, we need to setup the ipsec tunnel with loopback interface on Quantum Spark. Although the tunnel is up and working fine while we setup with WAN interface, it's failed with Loopback interface. When i captured the traffic at peer side, the packets are still coming via WAN IP, not via Loopback IP. I have attached the overview diagram and please let me know any additional configuration to add.

Which Check Point SK or Admin Guide did you follow ? Never heard of VPN from Loopback IF...

We have worked with three TAC engineers (three tickets) since March 2024. If this setup isn't supported, the TAC engineers should have informed us.

So far, there is one ongoing ticket, and they are still instructing us to change settings in Advanced Settings and report back, and it has continued like this until now.

Hope you find a solution soon!
