The Dynamic DNS / Enable registration of DHCP client names in DNS under Services: DHCP is what I think I need. It is my understanding that with this option, when a DHCP client receives an IP addresses from pfSense, pfsense then registers their names and IP addresses with the DNS server. Is this correct?
I don't know what you mean by Dynamic DNS / Enable registration of DHCP client names in DNS under Services: DHCP
. I can't find that on my system which runs pfSense 1.2.3-RC2 of 16-Jun 2009
I understand a DHCP request CAN include a system name and that name can then be used by pfSense to register a DNS name. My home Win2K, Windows Vista, Centos and Ubuntu Linux systems all provide such names.
The home systems whose names I care about are all assigned static DHCP addresses (the address DHCP provides is keyed to the MAC address the request comes from) so I've checked Register DHCP static mappings in DNS forwarder
but not Register DHCP leases in DNS forwarder
. Perhaps you would want the inverse of what I use.Dynamic DNS
often refers to a service of some name servers on the internet which allow systems which have an dynamic IP address (e.g. their internet visible address is assigned by DHCP and changes from time to time) to register their IP address through a special URL. Examples: DynDNS and OpenDNS. Home and small office networks often have a dynamic IP address and this mechanism allows them to register a name for easier access. For efective use of such a name service its often necessary to add some some software to track address changes. As far as I know there is no Dynamic DNS service (in this sense) on pfSense.
