Appendix #5 – Network Connectivity Overview
Router Port Forwarding (Step #4)
You will need to enable port forwarding on your Router to allow for external communications with your Observation System for ports:
•PORT 8841
Computers, DVRs, 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.
NETWORK EXAMPLE
Router Internal IP 192.168.0.1
Router Internal IP 192.168.0.1
Computer
Internal IP 192.168.0.102
DVR Internal IP 192.168.0.103
INTERNET
INTERNAL NETWORK
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 this data is to be sent to. This is where setting up Port Forwarding becomes important.
Port Forwarding tells the router which device on the internal network to send the data to. 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 216.13.154.34:6100 to DVR Internal IP 192.168.0.103:6100).
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 Support website at http://www.lorexcctv.com/support for more details
