Hello, We are upgrading our Network infrastructure and replacing it with all Cisco Meraki gear. we gonna use MX100 for the firewall and VPN access site-to-site and VPN client. we currently using the Active Directory for authentication with our Windows RRAS server. As per the documents I'm pretty sure we can configure the MX100 to authenticate using the Active Directory and then we can get rid of the Windows RRAS server. Can someone confirm this design will work or if we need extra equipment or setup? ANyone has it working?
