Hi @Ilovecheckpoint
I don't know the exact situation (peers are CP it 3rd party), but when I set GW managened on its external IP.
So it was someting like that:
site1 (management) <-- VPN tunnel --> site2 (VPN peer IP is the same as the MGMT IP that reaches the Management)
This two SK helped me a lot:
After enabling 'Exclude gateway's external IP addresses from the VPN Domain' VPN Tunnel is down

VPN Site-to-Site with 3rd party
Scenario 3 - Implied inclusion of Check Point Security Gateway's / 3rd party VPN Peer's interfaces

The sk108600 is not trivial, read carefully before do anything.
I hope it helps.
