Dynamic DNS

Dynamic DNS provides a convenient way to access mobile SIM routers remotely over the internet, even when it has a cellular carrier-assigned IP address that changes periodically.

A Dynamic DNS service maps a static hostname or domain name to the router's frequently changing public IP address. This allows remote connection to the router over the internet by using the fixed hostname without knowing the latest assigned IP.

Most consumer cellular connections use private carrier NAT IP addresses instead of public internet routable addresses. You need to enable a public IP assignment from your cellular data plan before DDNS will work reliably.

To configure DDNS, log into the OutdoorRouter web admin interface and navigate to "Services > Dynamic DNS". Enable the DDNS client feature and select which DDNS provider service you have created an account with. Enter your credentials for authentication. Multiple provider options are available in the dropdown menu.

Remember to click "Save & Apply" after entering settings to activate the DDNS client service. When enabled, it will automatically update your DDNS provider with any new public IP address the 4G/5G cellular carrier assigns, keeping the hostname linked to the router.

Alternatively, if the DDNS function is for accessing the OutdoorRouter remotely, suggest using the free integrated Traversal Cloud function. You can enable it under "Services > Traversal Cloud". It provides a secure encrypted tunnel to your router without public IP.
