Dynamic DNS
Dynamic DNS provides a convenient way to access Mobile SIM card routers remotely over the Internet, even when they have a cellular carrier-assigned IP address that changes periodically.
DDNS, short for Dynamic DNS, maps a static hostname or domain name to your router's public IP address and updates the IP address automatically when the public IP changes. Thus, you can connect to your router remotely using the fixed hostname without knowing the public IP address.
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.
After logging into the OutdoorRouter web admin interface, go to "Services > Dynamic DNS".
Enable the DDNS function and choose the DDNS provider service. Enter your authentication credentials. The dropdown menu offers various provider options.
After saving and enabling the DDNS service, it will automatically update your DDNS provider with any new public IP address the cellular carrier assigns, keeping the hostname linked to the router.
Example of Setting DDNS
Below is a step-by-step example of how to connect the mobile SIM router to NOIP's free DDNS service.
DDNS Hostname on No-IP
Visit noip.com, create a free account, and log in.
Navigate to "No-IP Hostnames" on the left menu bar, and click the "Create Hostname" on the right side.
Hostname - Choose a hostname as the subdomain in the access URL.
Domain - Choose the Domain name to bind to the DDNS service.
Record Type - Select the first DNS Host (A Type).
IPv4 Address - Use the public IP that is automatically obtained. It will auto-sync with the mobile router's public IP after configuring the DDNS client.
Click the "Create Hostname" button to finish the account setting.
DDNS Client on the Router
Connect to the outdoor router by WiFi or wired LAN and log into the router admin.
Navigate to "Services > Dynamic DNS." Enter a new DDNS configuration in the input box and click the "Add" button. It will jump to the configuration page.
Enable - Tap the checkbox to enable the DDNS service.
Lookup Hostname - Enter the No-IP Hostname and Domain created above
IP Address Version - Use the default IPv4 Address.
DDNS Service Provider [IPv4] - Select no-ip.com as the provider. Or choose the other DDNS providers from the dropdown list.
Click the "Change Provider" to input further parameters.
Domain - Use the domain name chosen in the above hostname step 2.
Input your DDNS provider's account username and password.
Click the "Save & Apply" button to finish the configuration.
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.
