DDNS
For the device's Dynamic DNS settings:
- Services
- Dynamic DNS
follow the menus. The DDNS (Dynamic Domain Name System) function provides remote access to the router via a domain name instead of your occasionally changing dynamic IP address. This way, remote access operations are not affected by changes in your IP address.
Supported Services
If you can select your DNS service provider from the Services section, you can configure it as follows:

| Parameter | Description | Default Value |
|---|---|---|
| Enable | On/Off | Off |
| Effective Interface | lan/wan_wired/wan_4g | lan |
| Service | DDNS server address | dyndns.org |
| Hostname | Enter the hostname provided by the DDNS server | mypersonaldomain.dyndns.org |
| Username | Enter the username provided by the DDNS server | myusername |
| Password | Enter the password provided by the DDNS server | mypassword |
| Source of IP address | Network/Interface/URL | Interface |
| Interface | eth0.2/eth1 | Eth0.2 |
| URL | Select the IP source of the URL address | http://checkip.dyndns.com/ |
| Check for changed IP every/unit | The interval at which IP address changes are detected. The IP binding of the domain may change frequently, and the lower the value, the more frequent the detection. | 10 min |
| Force update every/unit | Time interval for mandatory updates | 72 h |
Custom Services
If your DNS service provider is not listed in the Services section, select the Custom option and configure it as follows:

In this section, the ddns.oray.com service is used as an example.

- After setting all parameters, do not forget to restart the device for the parameters to take effect.
- Dynamic domain names work even if the router is on a subnet.
- DDNS + port forwarding can provide remote access to the router's subnet.
- A separate public IP address must be assigned to the router's network for this function.
