Description

In the Dynamic DNS section It's not possible to update an address with the CARP address, IT's only possible to update the dynamic with the addresses of the physical interfaces. In HA mode it would be useful to add virtual IP as well.

CARP addresses will always be static. What purpose will this serve?

If it's for Multi-WAN failover, pick the CARP address in the failover gateway group, then use that gateway group for Dynamic DNS.

In High Available it is useful when you want to update / modify DNS from a single point without having to move to the Dynamic website.
When creating multiple VPN tunnels, clients must point to the address of the carp and not to the WAN address.
Currently I can not ask the PFSense to update the "static" CARP address in the Dynamic DNS

Currently the WAN also has the static address
In any case, I update the Dynamic from the PFSense so if I had to change the WAN address, the dynamic and the related VPN tunnels are automatically updated as well.

Eg:
Scenario with two firewalls in HA

Subnet x.x.x.224 / 27

CARP address: x.x.x.230 / 27

pfsense 1:
WAN address: x.x.x.228 / 27
dyndns: AAApfsense1.dyndns.org

pfsense 2:
WAN address: x.x.x.229 / 27
dyndns: AAApfsense2.dyndns.org

Currently if you vary the static addresses of the wan, the pfsense automatically updates the relative dns. If the CARP address varies I can not create any rules to update the dynamic DNS.

Eg:
dyndns: AAA.dyndns.org with CARP Address.

It makes sense to have in pfsense the possibility to select in the Dynamic DNS CARP interface for high availability in VPN, whoever has installed lost this possibility. I can send more information.

This option "CARP address in the failover gateway group, then use that gateway group for Dynamic DNS" is not possible.

Hi Jim. Sorry for bumping this up, but the current implementation still lacks of this functionality and does not allow to use DynDNS in multi-homed HA configurations.

If it's for Multi-WAN failover, pick the CARP address in the failover gateway group, then use that gateway group for Dynamic DNS.

I wasn't able to find how to pick the CARP address on the gateway group configuration page. Please, advise
