I have an interesting question for you. I search several stack forum to find an answer but I could not able to find anything completely related. I have a rpi and I am using this device as sensor data collector. Let's say its ip address is (eth0). It constantly sends the sensor data to a server, so I can not change ip of it.

Also I have a camera, which connects with ip link. Let's say it connects with I want this camera to connect my network; however, I have to establish just one connection with both rpi and camera. So I am aiming to connect the camera to RPi by ethernet to usb converter(eth1) and set a switch configuration on my RPi to continue sending both sensor and camera data on eth0.

Basically, I want to build an ip switch on rpi, which is going to send sensor data by ip address and camera data from eth1 by ip address.

Is it possible? or what are the suggestions, which can help me?

ps: I have no wlan connection, so wlan related ports are not possible. ex: wlan0.

  • Is this the scenario; Your Raspberry is connected to a router/firewall with eth0, and the Camera is connected to eth1 on the Raspberry Pi?

  • Similar actually, eth0 is connected to a device, which acts as a router, however; it has no dhcp protocol.

To solve this you can use bridge-utils. With bridge-utils you can bridge two or several interfaces together.

  1. Install sudo apt-get install bridge-utils

  2. Edit /etc/network/interfaces so it will look like somthing like this

iface eth0 inet manual

iface eth1 inet manual

# Bridge setup iface br0 inet static bridge_ports eth0 eth1 address broadcast netmask gateway

And then restart the network service service networking restart

This will bridge eth0 and eth1 into a bridge br0 and set the IP adr. on the br0 to and blank the IP ad. on eth0 and eth1.

Router | | +--------------+ +--------+ | | Raspberry Pi | | | | | | | Camera | | | br0 | | | | +--+------+----+ +----+---+ | eth0| |eth1 | | | | | \-------- \---------------

  • I believe this will help me a lot, but I have a question for you, how can I access the camera from a device, which connected to the router with ip? I believe I have access to the data on rpi by but I did not understand how to connect camera from a device on the router by ip. Consider that, I will connect a pc to the router (pc ip is irrelevant) and I want to see camera interface on that pc, when I write on a browser. How can I add this step to the steps you explained above?

  • The bridge is a switch (two ports only), so the traffic on eth0 is the same as on eth1. As the schema in my answer shows, you connect the camera to eth1 on the Raspberry Pi and give the camera the IP
