Before You Start

Port forwarding should only be used when the devices need to be accessed via the internet. To ensure proper security configuration, please follow below points:

1. Minimize the port numbers exposed to the internet. Port forwarding should only be configured when absolutely necessary. For example, to use web service, only port 443 should be forwarded.

2. Avoid common ports and reconfigure them to customized ports. For example, port 80 is commonly used for HTTP. User is recommended to change to a customized port on the device other than port 80 for the designated service, following TCIP/IP port rule (1 – 65535).

Instructions

1. Network Topology

At first, you should connect your device in accordance with the followed image:

2. Ports to be forwarded

Generally speaking, you need to open all the three http, rtsp, server ports, 80, 800, 554 are as default. You can find the port number via web:

For back-end device, you can also find the port number in "More Settings" locally.

3. Open ports in router

You can select to open ports manually, or use the UPnP to open ports automatically. Open ports manually is more reliable. It’s because in the UPnP mode, external ports are assigned by the router automatically, there might be ports conflicts if there are many devices in your network.

Open ports manually:

Steps:

1) Login your router, go to Forwarding->Virtual Servers;

2) Click Add New to add ports;

3) Input the port number, IP address(which is the same with your IPC/NVR), select Protocol as ALL;

4) Repeat the step to open all the three ports

Open ports automatically:

Steps:

1) Login your router, go to Forwarding->UPnP, enable it; (this funciton is enabled as default for many routers)

2) Login your IPC/NVR via web, go to Configuration->Network->Basic Settings->NAT, enable UPnP, select the Port Mapping Mode as Auto.

3) Refresh the page, all the parameters like External Port, External IP address will be filled automatically. If the Status turns to Valid, it means the configuration is done.

Note:

1) DMZ function is suggested to be Disabled;

2) Different routers may have different interfaces; but the precedures are the same.

3) The default No. of Server Port (for client software viewing) is 8000, which can be effective from 2000 to 65535;

4) The default No. of HTTP Port (for PC web viewing) is 80, which can be effective from 1 to 65535;

5) The default No. of RTSP Port is 554 (for data transmission), which can be effective from 1024 to 65535.

6) Sometimes 80 or 8000 may be occupied by some other applications, so you may change them respectively to 81/82 or 8001/8002.

7) If you modify 80 to any other No., you need to input “Colon + Port No.” after the public IP or address in the web browser when you try to access your device via web, such as http://57.63.91.xx:81.
