How to Configure DDNS on OpenWrt
TABLE OF CONTENTS (Nhấn để xem)
Many services provide DDNS, and each service has its own configuration and usage policy. This guide uses Cloudflare for a domain you already own and manage through Cloudflare. Other DDNS services follow a similar process.

Forced update successful - IP: '171.225.xxx.xxx' send indicates success.
The service checks and updates the address automatically at regular intervals.

| Password | DuckDNS token | Get the token from the DuckDNS account |
| Path to CA-Certificate | /etc/ssl/certs |

Other DDNS services can be configured in the same way; replace the domain, username, and password with values required by that provider.
Tutorials may have been written for older OpenWrt releases, so menu names can differ on newer versions. Check the current documentation if an option is missing.
