2. Understanding Port Forwarding or Port Mapping?
Vodafone assigns one IP address to your internet connection. All computers on the internet need a unique IP address, but you have multiple computers connected to the internet. So how does this work?
IP addresses is a unique name assigned to a device (cctv, laptops, phones, printers)
Port - it is the end point of communication (source of a service) within a network and each port is associated with an IP address.
With the combination of a port number and an IP information can be sent or retrieved from specific servers providing a specific service 
Ports are represented in number format and each port number is used to identify a specific service.
For example most service uses tcp port 25 for incoming request and this service can be redirected to another port number and IP combination for a number of reasons like a more secure data transfer. 
Network Address Translation allows each device on your network to have its own IP address.
While each device in your network has its own IP address, from the outside, every request coming out of all of those devices appears to be coming from the single publicly visible IP address assigned to you by your Internet Service Provider.
