Hi ,

I am experiencing issues with remotely accessing my IP camera's RTSP feed using a No-IP domain on my TP-Link MR6400 router.

Below, I have provided detailed information about my setup and the problem I am facing.
 

1. IP camera: Foscam IP camera connected to the router's network
2. No-IP setup: I have configured a dynamic DDNS with No-IP as the provider, and the domain name is mapped to my router's IP address.
3. Port forwarding: I have enabled port forwarding in the router to redirect requests to the Foscam IP camera. Two ports are configured: an external port (1818) and an internal port for the camera (88).
4. RTSP URL: I have constructed the RTSP URL using the No-IP domain, external port (1818), and the camera's RTSP path.
5. Local network access: I can successfully access the RTSP feed using the router's public IP address within the same network.
6. Remote network access: I am unable to access the RTSP feed using the router's public IP address or the No-IP domain from an external network.
    
7. IP address discrepancy: The WAN IPv4 IP address displayed on the router does not match the IP address shown in the No-IP portal but its same as whats my IP website IP address probably thats the issue also and router WAN IP start with 10.
8. tried setting up  open vpn also but getting connection timeout from outside network from a open vpn client 
    

I have already attempted the following troubleshooting steps:

1. Double-checked port forwarding settings on the router.
