Private IP (Dedicated IP)
Private IP is useful when you need to access complex applications and services such as, games, file transfer (BitTorrent), communication applications (Skype), etc.., that require dedicated IP address (fix IP address). With private IP address, you don’t have to worry about port forwarding any more, it’s all done for you automatically. When you purchase private IP, you are connected to a dedicated IP address, and not shared IP address on the network. This is another advantage to you, as you will appear as a private individual network device and not as a shared network device.

NAT Firewall
NAT Firewall blocks outside hosts from creating unsolicited connections to your host. Also you can port forward up to 3 ports, which then you can use to access complex applications and services such as, games, file transfer (BitTorrent), communication applications (Skype), etc..
