ipsec INVALID_MAJOR_VERSION

[mliebherr]

Hello,

since about yesterday i get those errors in my logs:

Code Select Expand


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:



Cheers,
Mario
