Cloudflare Not Allowing "*" Hostname Entry in Dynamic DNS
Cloudflare allows wildcard A records and the pfSense DDNS page has a wildcard checkbox (since 2.3?), but it will throw an "invalid hostname" error if you provide a "*". This can be circumvented with a direct edit on the config xml, but it's certainly not ideal.
- hide wildcard and MX checkboxes since neither are used by the Cloudflare code
- update the call to is_domain() to have a truthy second argument, allowing wildcards for cloudflare and cloudflare-v6
Unlike the recent related Route53 and Linode edits, i have not tested this change.
