If you encounter a scenario where you're unable to forward a network request back to the same network using a domain name on the WAN IP address, you can follow the guide below to manually set up NAT Loopback.

Note:
1.Require a domain name for your WAN IP address.

2.The mapping ports on external and internal ports must be the same
Ex: public port: 8001, local port: 8001.

3.The DNS server for clients must be SCR 50AXE.

The following steps will guide you on how to make NAT loopback work using DDNS:

1.Go to NCC > Configure > Security Router > Router Settings to configure Dynamic DNS.

2. Set up the DDNS name in the DNS Address Record, then map it to the IP address of the LAN server.

3. In NCC > Configure > Security Router > Firewall > NAT settings, ensure that the public port and local port are the same.
