Hello,
since about yesterday i get those errors in my logs:
charon 53061 - [meta sequenceId="4143"] 03[NET] received unsupported IKE version 11.9 from 212.185.79.66, sending INVALID_MAJOR_VERSION
charon 53061 - [meta sequenceId="4148"] 03[NET] received unsupported IKE version 3.5 from 212.185.79.66, sending INVALID_MAJOR_VERSION
charon 53061 - [meta sequenceId="4152"] 03[NET] received unsupported IKE version 0.13 from 212.185.79.66, sending INVALID_MAJOR_VERSION
And the traffic of the tunnel seems to stop.
Any idea how i can fix that? The Remote Side has a Sophos UTM and claims not to have/see any errors.
My Last Update was done more that one day ago ( i guess last week).
Any hints on this?
I also wonder why i get two subnet tunnels here. One Installed, and one rekeying:
