Network bridging describes the action taken by network equipment to allow two or more communication networks, or two or more network segments, to create an aggregate network. Bridging is distinct from routing which allows the networks to communicate independently as separate networks. A network bridge is a network device that connects multiple network segments. In the OSI model bridging acts in the first two layers, below the network layer.
There are four types of network-bridging technologies: simple bridging; multiport bridging; learning, or transparent bridging; and source route bridging.Transparent bridging was originally developed by the Digital Equipment Corporation (DEC) in the 1980s
“A device used to connect two separate Ethernet networks into one extended Ethernet. Bridges only forward packets between networks that are destined for the other network. Term used by Novell to denote a computer that accepts packets at the network layer and forward them to another network.”
The MAC Bridge
Bridges are used to connect LANs. Therefore in determining how to transmit traffic between LANs they use a destination MAC address. Bridges pushes the function of network layer such as route discovery and forwarding to the data link layer. There is no conventional network layer for bridge.
The bridges can not maintain the data integrity. For example suppose there is a error in one frame and that frame is not transmitted properly the bridge will not give any acknowledgement to retransmit that frame. If the bridge becomes congested the frames can be discarded to make the traffic smooth. On the other hand the bridges are easy to implement and no need to configure them.
How to make Bridge Connection
1. Go to Network Connection
2. Select 2 or more LAN Connection (you need to press CTRL on keyboard then click left on mouse when selecting )
3. After selecting right click then choose bridge connections
Please do not use wifi this is sample only
When done you will see this
Note: if you don't want to use this just delete the MAC Bridge Mini port to delete all setting you made.
How to make your WiFi to LAN using OpenVPN
1.First connect to wifi
2.then connect open vpn
(your tap 32 must visible on Network Connection)
If you using hotspot shield unhide it
3. Create a bridge
