Types of Routing

Network connections 

Network connections are the types of connections through which a network connects to the internet or the local isp.

It ensures the security of the network and privacy.

There are four types of network connections 

NAT CONNECTION

BRIDGE CONNECTION 

NAT + BRIDGE CONNECTION

DOUBLE NAT CONNECTION

NAT connection:

    NAT connection is abbreviated as National Address Translation, it converts the public IP address to a private IP address. 

    it adds security to the network by keeping the private IP addresses hidden from the outside world.

Types of NAT

Open NAT: This implies that your gaming console can connect to other people's games, host games, and other users can find and connect to the game you're hosting.

Moderate NAT: This indicates that your connection to other players is neither restricted nor unrestricted. You'll be able to communicate with other players, but some features will be restricted.

Strict NAT- This means that you have limited connectivity with other players and players who have Strict or Moderate NAT will not be able to join your gaming session

Bridge Connection:

• Bridge mode is a networking feature that enables two routers to communicate with each other.
• It effectively converts the relevant router into a switch once it is enabled.
• The bridge-enabled router will continue to send and receive data, but it will no longer fulfil standard Network Access Translation (NAT) functions.
• Instead, the bridge-enabled router will grant linked devices access to its ports.

NAT + Bridge Connection:

In some cases the ISP provider will provide a switch with NAT configuration. In those cases we can use our personal router as a bridged switch so that the DHCP server in the NAT configured router will provide the IP address to the switch and the switch will redirect it to the node(device)

Double NAT:

    When two or more routers on a network execute Network Address Translation (NAT), this is known as double NAT. Double NAT (also known as double routing) has no effect on computer or web browsing, but it might cause problems with VoIP services.
