Port forwarding illustration

Before you understand what is port forwarding, you need at least basic understandings for below concept:

#1 IP addressing

#2 What is switch and router

#3 Inside network and outside network

Basically when you sign up a Home Internet plan with your service provider, you are provided with a router a.k.a router or gateway.

This device connects you to the Internet. You can either connect yourself to the router using LAN cable or WIFI method.

Everything works fine until you want to access your Home IP Camera remotely. You may be at office or travelling at foreign country. For example, you can still accessing to the IP Camera as long as you have internet connection, 4G or broadband connection.

Be default, due to the security, the router will not allow you to access inside network when you are at outside network. You can only access Internet (outside) when you are at home (inside) OR you want to access the IP Camera (inside) when you are at Home (inside).

To overcome this problem, you need to configure Port Forwarding in the router.

Below is a detailed diagram that shows the overall progress when you want to access the IP Camera via the Port Forwarding method.
