Hi,
I'm trying to establish and IPSEC (S2S) tunnel between 2 managed Check Point firewalls. I previously succeeded with the same kind of HW/version. This one throws an error I've never seen before :
Main Mode Failed to match proposal: Transform: SHA1, Certificate, Group 2 (1024 bit); Reason: unsupported encryption algorithm -1 (NA)
I've tried lowering the algorithm, still the same issue.
Any idea how to troubleshoot that ? I'm currently planning on upgrading that remote GW to the latest available firmware, and rebooting it.
Thanks !
