I was trying to configure a GRE Tunnel over VPN IPSEC, between an Aruba SD Branch and a Watchguard, but was unable to establish it.
Has anyone set up this tunnel?
Regards.
Have you tried the settings that follow 'pass-through' tunneling with a cloud endpoint?
Seems like the answer is hidden. Specific IPSEC configurations can then be applied. I'm interested to know if you have succeeded. I'm facing a similar question.
