Hello, I am experiencing a problem in my current project. My client is replacing the pfSense firewall with a Cisco Firepower 1140. The client only has a dynamic public IP address, as was previously configured in pfSense through DDNS for SSL VPN.
I am wondering how I can use DDNS in the Cisco Firepower 1140. Please note that there is no FMC (Firepower Management Center) in the environment, and I am using FTD (Firepower Threat Defense).
Could you please help me resolve this issue?
