We upgraded our RB1100AH2x yesterday from 6.19 to 6.22 and lost our L2TP / IPSec tunnels in the process. The logs are now littered with IPSec errors stating
failed to pre-process ph2 packet.
In the change log for 6.21 I notice that you can no longer employ a blank value for the Policy Group in the Peer policy. We had originally configured our tunnel this way and I suspect that this is the cause of the errors.
Can anyone point me in the right direction on how to resolve this issue?
See relevant config below (note that the first entry in the ipsec peer is note relevant - entry "1" is the one I am most concerned about

You have to delete the group, which is in the IP/ipsec groups.
Then it will say unknown in the peer tab. After that, it should work.
