Any thoughts on what it would take to leverage the Dynamic DNS Updater in OPNsense having it query for the external IP as opposed to using the IP on the OPNSense device itself? I've got an OPNSense device that's actually behind NAT acting as a point of termination for a Wireguard Tunnel. Currently my solution is a VM running a linux instance on the WAN Network subnet that is running a DynDNS updater client to check and update my Dynamic IP's/Hosts regularly. However, I'd like to have OPNSense handle this function, but the DynDNS updater in OPNsense doesn't seem to support this feature as it only is seemingly able to query interfaces it knows about.
Thanks in advance....
