 **Dynamic DNS**                     Enable Dynamic DNS. This option needs the `General Settings - DNS Provider` configured. The DNS Records of this domain will be automatically updated with the chosen DNS Provider.
 **>Trust**                          Certificate options
 **DNS-01 challenge**                Enable this for using DNS-01 instead of HTTP-01 and TLS-ALPN-01 challenge. This can be set per entry, so both types of challenges can be used at the same time for different entries. This option needs the `General Settings - DNS Provider` configured.
-**HTTP-01 challenge redirection**   Enter a domain name or IP address. The HTTP-01 challenge will be redirected to that destination. This enables a server behind Caddy to serve ``/.well-known/acme-challenge/``. Caddy will issue a certificate for the same domain using the TLS-ALPN-01 challenge or DNS-01 challenge instead. Please note that his is a complex scenario, Caddy can *only* continue to get automatic certificates if it can listen on Port 443 - so either specify 443 directly or leave the Port empty. Having the domain listen on any other port than 443 will mean the TLS-ALPN-01 challenge will fail too, and there won't be any automatic certificates. If the requirement is a different port than 443, the DNS-01 challenge will remain the only option.

This option can also be used to redirect the HTTP-01 challenge to Caddy on a backup OPNsense firewall in a HA setup.
 **Custom Certificate**              Use a certificate imported or generated in `System - Trust - Certificates`. The chain is generated automatically. Certificate + Intermediate CA + Root CA, Certificate + Root CA and self signed Certificate are all fully supported. Only SAN certificates will work.
 **>Access**                         Access options
 **Access List**                     Restrict the access to this domain to a list of IP addresses defined in the Access Tab. This doesn't influence Let's Encrypt certificate generation.
