How do I access my devices remotely from the Internet? (DDNS / WAN access)
Dynamic DNS (DDNS): go to Advanced > DDNS > Add. Select your provider (noip.com, dyndns.org, etc.), enter your domain name, WAN interface, and account credentials. Combine with Port Forwarding to reach specific services.
Warning: Remote access exposes your devices to the Internet. Use strong passwords and only enable when strictly necessary.
