Appendix D: Router Port Forwarding - Lorex LNE1001 Instruction Manual

APPENDIX D: ROUTER PORT FORWARDING

In order to view the device remotely (over the Internet), follow the steps outlined on the following
pages to setup a free DDNS Remote Access account.
You will need to enable port forwarding on your router to allow for external communications with
your device. The following ports will need to be forwarded to remotely connect to your device:
• Video Port 554
• Web Port 80
Computers, IP cameras, and other devices inside your network can only communicate directly
with each other within the internal network. Computers and systems outside your network cannot
directly communicate with these devices. When a system on the internal network needs to send
or receive information from a system outside the network (i.e. from the Internet), the information
is sent to the router.

Figure 31.0 Network example with port forwarding
When a computer on the Internet needs to send data to your internal network, it sends this data
to the external IP address of the router. The router then needs to decide where to send this data.
This is when Port Forwarding becomes important.
Port Forwarding tells the router to which device on the internal network to send the data. When
you set up port forwarding on your router, it takes the data from the external IP address:port
number and sends that data to an internal IP address:port number (i.e Router External IP
216.13.154.34:554 to IP Device Internal IP 192.168.0.3:554).
NOTE: If using multiple IP Devices on the same network, you need to assign a different remote access
port for each device.
The instructions found online in the Router Configuration Guides will assist you in the port
forwarding configurations for a selection of different router models. Visit our Consumer Guides
