DynDNS: Hostname '@' not accepted for Namecheap
When you try to create a dynamic DNS entry for '@' as per Namecheap's DNS configuration, pfSense gives an error "The Hostname contains invalid characters."

If you want to add wildcard, you must type *.yourdomain.com, it's not working in pfSense because of "The Hostname contains invalid characters."
Can you fix this also ?
