I have purchased and hosted a domain through Cloudflare. (example.domain)
I currently have two type A records in my DNS records. They are router.example.domain and vpn.example.domain. These IP addresses are updated through the Dynamic DNS feature built into pfSense. I am then using ACME to generate certs for those domains. These are working correctly.
I am looking to setup a Jellyfin/Plex server and Synology and want to use HAProxy to handle the certificates and everything will be accessed internally only, I’m not exposing anything to the internet.
However. I don’t want to keep adding A records to my DNS for every subdomain. So I am attempting to point a wildcard (*.example.domain) to my pfSense router using the DynamicDNS feature, but it is failing. The dynamicDNS service is not syncing with Cloudflare. The pfSense documentation mentions about enabling Wildcards for the dynamic DNS but I don’t see a check box for that when setting up the dynamic DNS entry in pfSense.
I’m also not sure if I need to remove the other 2 dynamic DNS entries to get the wildcard to work or if they can coexist.
