Bridge mode definition
Bridge mode is a network configuration where a networking device acts as a pass-through solution rather than as a router. When the device is In bridge mode, it becomes an interface between two separate networks, allowing them to communicate.
A device in bridge mode has no routing or Network Address Translation functions. Instead, it passes network traffic between two networks without modifying or analyzing the data packets. Bridge mode is commonly used when a user wants to extend their network without creating conflicts or duplicating network services.

Bridge mode use cases
- Extending Wi-Fi coverage. By placing the device in bridge mode, it acts as a Wi-Fi repeater or range extender.
- Integrating multiple networks. In some cases, a user may have separate networks in different locations that need to be connected. Bridge mode allows them to connect these networks without complex routing configurations.
- Using specialized networking equipment. Some network devices, such as firewalls, security appliances, or virtual private network (VPN) concentrators, require direct access to the public internet without network address translation (NAT) or other routing functions. By placing the router or modem in bridge mode, you can provide these devices with a public IP address and allow them to operate as intended.
- Troubleshooting network issues. By isolating a device or network segment from the rest of the network, you can test and diagnose connectivity or performance issues without the interference of other network components.
