Create a network bridge
A network bridge is software or hardware that connects two or more networks so that they can communicate. You can create only one network bridge on a computer, but one bridge can handle any number of network connections.
Open Network Connections by clicking the Start button , and then clicking Control Panel. In the search box, type adapter, and then, under Network and Sharing Center, click View network connections.
Hold down the Ctrl key and select each network connection that you want to add to the bridge.
Right-click one of the selected network connections, and then click Bridge Connections.
If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
