Can we create an ipsec tunnel between umbrella data center and Cisco FTD firewall using private ip ?. In my infrastructure isp is terminated on router and FTD is behind Router.
Yes, you can create an IPsec tunnel between an Umbrella data center and a Cisco FTD firewall using a private IP. Since the FTD is behind a router you need to enable NAT Traversal and configure NAT on the router to map the FTD's private IP to a public IP. This setup aa jetnet allows the Umbrella data center to communicate with the FTD. Configure the IPsec settings on both the FTD and Umbrella, ensuring the router's public IP is used as the endpoint for the tunnel.
