6.6 Router & Port Forwarding

A majority of networks will often consist of a single IP address which shares internet access

through a router. This IP address may be any external (public) static IP address or any

dynamic IP address issued by the Internet Service Provider.

The purpose of a router is to enable multiple personal computers and any other devices that

require internet connection to access the internet simultaneously. Most routers by default

enable (open) commonly used ports so that mainstream applications such as Hypertext

Transfer Protocol (HTTP, Port 80), File Transfer Protocol (FTP, Port 21), Telnet (Port 23) and

Post Office Protocol 3 (POP3, Port 110) are used.

To solve the firewall problem, and let a visitor into the network, the user instructs the router to

allow traffic to pass through on a given port. This is known as Port Forwarding, as the router

forwards (directs) all internet requests on a specific port to the local machine. With port

forwarding, external visitors are able to connect to the DVR while other internal devices

remain protected.

Here is the example of DVR connection.
