@akan33  Have you talked with support about beta 15.7 and the change it made to the Anti-replay value from 4 to 32?  I do not know ASA, is it possible to change it's value down to 4 to match the Meraki's pre-15.7 value? ... View more

@ITofTN you are going through the same steps I did for 4 months.  Have your Meraki guy look up my Case 02390711 and talk to the engineer on it.  From your description the Anti-Replay is the issue.  We did the NAT-T thing also with no success. ... View more

Juniper has a default value of 64. We have requested that this be a configurable value either to the end user or the Support staff. After applying the beta code all has been smooth. We are still working out a few Dead Peer detection issues, on lesser used subnets. ... View more
