Good evening.  Looking for anyone that has experience, tips, info on PCI compliance and how it may pertain to the Meraki MX64.  I have a small body shop as a customer and they had PCI compliance test done and failed.   The vulnerability was: Internet Key Exchange (IKE) Aggressive Mode with Pre-Shared Key port 500 / udp / ikev1   THREAT: The remote IKEv1 service supports Aggressive Mode with Pre-Shared key.   IMPACT: The remote Internet Key Exchange (IKE) version 1 service seems to support Aggressive Mode with Pre-Shared key (PSK) authentication. Such a configuration could allow an attacker to capture and crack the PSK of a VPN gateway and gain unauthorized access to private networks.   SOLUTION: - Disable Aggressive Mode if supported. - Do not use Pre-Shared key for authentication if it's possible. - If using Pre-Shared key cannot be avoided, use very strong keys. - If possible, do not allow VPN connections from any IP addresses.   Does this necessarily happen at the MX?  Comcast Business is the ISP ahead of the MX and the workstations each run Kapersky or WinDef for antivirus/firewall.   Thank you in advance for any tips or advice. ...
