We have a site with a Meraki MX that site to site VPNs and client VPN behind another firewall that Nat's the traffic to the MX. the site to site VPN's work however not the client VPN. Any ideas what may prevent the client VPN to work? I would assume if site to site VPN works that the outside is able to reach the MX on ports UDP 500 and UDP 4500.
