Hi, I consider to deploy FreeIPA in my home network. In this network I run several servers and workstations with both Linux and Windows. In addition I have setup some Webservices running in containers (LXC). I have only one public IP and manage the (privately hosted) Webservices with a reverse proxy. The network architecture includes several networks, e.g. LAN, DMZ, ... All networks are secured by relevant iptables roules.
I want a central user management strong security management. This is included in FreeIPA.
In addition FreeIPA includes some network related features, e.g. DNS.
And here starts my problem. Currently I manage the DNS of my public domain with the domain provider. If I install FreeIPA I need to shutdown the DNS management with the domain provider and manage this by myself. Can I shutdown this DNS service before starting FreeIPA installation w/o impacting DNS resolution to my domain? What happens if FreeIPA is down? Should there be any redundancy?
