By using port mapping (NAT) rules on the router, you can choose to forward the surveillance system's HTTP/HTTPS ports only on the LAN interface and leave them closed on the WAN side. This ensures users on the local subnet can access the camera interface via its IP address, while external login attempts from the internet are blocked.
