HI,
I never leave replies for anything but this is really helped me out. I have 12 locations with ASAs and couldn't figure out why they kept dropping. Made the changes you mentioned and have had solid tunnels. Meraki really dropped the ball on that tutorial.
Many thanks
@wirestyle22 I am replacing a 5515 at HQ with an MX84. I have 12 locations with 10 ASA 5505s and 2 Peplink devices. I also have a vpn connection from HQ to AWS. I have only had it up for the past couple days but it seems to be holding steady. The taking off of the NAT-T and changing the lifetime.
