Zkteco DL-854N28B [44/49] Port mapping

underlined in red. When the IP corresponds to the embedded IPC’s IP in Public internet, it means the DDNS is

setting right. If they are not, please check the network connection of embedded IPC and DDNS information.

5.2 Port Mapping

Port mapping is mapping a port of outside web host’s IP address to a machine inside web, and provide the

service. When user connects to the port of the IP, the server will automatically map the request to the

corresponding machine inside LAN.

With the function of port mapping, we can map many ports of a machine’s IP address to different machines’

different ports inside web. The port mapping can also have other special agent functions, like POP, SMTP, TELNET,

etc. Theoretically, it can provide more than sixty thousand ports.For example, if we want to map a web server

which has an IP address of 192.168.111.10, we just need to input the IP address and TCP port 80 into the port

mapping chart of the router.

There are two ways to map the port: UPnP function of automatically map and modify the router’s port mapping

chart by manual.

5.2.1 UPnP Function

In order to get connection to the Embedded IPC through Public network, we need to set the Router to cross the

NAT of Embedded IPC. UPnP can make the NAT cross automatically by the UPnP agreement of Embedded IPC,

and don’t have to set the Router.

Note: to realize the UPnP Function, there must be Router support and enable the UPnP Function.

The first step

Connect the Router to the network, get to the Menu of the Router, set the Router, then get to port, and enable

the UPnP Function.

Routers made by different manufacturers may have some difference, please refer to the specification carefully

before setting the Router.

The second step

Connect the Embedded IPCto the Router; the configuration will automatically gain the IP address or static IP.

After setting up the IP, click the Advanced Config. And get to【the Network transmission capacity, ports and

multicast etc. 】to open the Enable at the 【UPnP port mapping】.
