LAN DNS update / change IP address not DynDNS Services

[rgo]

Just wondering if this is already built into opnsense.  Lets say you have the lan dns server handing out local ip to 192.168.1.x network for dhcp clients.  In that dhcp block everything is dynamic.  Outside of that block lets say 50-100 is dynamic and 101-200 is static address.

Lets say we have a system with 192.168.1.150 call abc.xyz.com and that system goes down.  Is their a way with opnsense to update the ip address of abc.xyz.com to 192.168.1.175???  Outside no one would know about abc.xyz.com because it is not on the public side of DNS or WAN addressable since it is private network.  I am only talking about private network side not the public side when everyone thinks about DynDNS that is public network.  I am not talking about public networks.

Just wondering if this it already in opnsense or its better to turn of LAN DNS in opnsense and setup a unix box with DNS Server to handle private dyndns updates and do all of what opnsense is doing for dhcp?

If anyone has done this in opnsense then I would like to see a config or setup of how you went about getting it working.

Hi rgo,

Isn't that what RFC 2136 is about? You can update local addresses with it.

How would you configure opnsense to do this?
