I'm looking to create a new bridge network(BR1), to connect to a new interface on my Unraid server, I have looked for the last couple hours for clear documentation on how to do this, unfortunately not able to find the info, as this topic comes up with a lot of info for creating docker networks. I have looked around the Unraid linux cli for the config file, but no luck.

What I'm trying to do is isolate a new network i have built out on my PFSense firewall to be utilized on VM's on the Unraid box, my existing config is eth0 is tied to br0 and shared to a few VM's and Docker containers, I want eth1 to have a similar configuration to br1, replicating what br0 does for eth0, but I need to create br1. how is this done? 

 

Ive already got the network built out from the PFSense firewall to the Unraid server, via newly configured ehtermet ports, directly cabled, just need this last piece, bridge network setup, to share this connection to a select few VM's.

The easiest way to is use a secondary nic. USB or Onboard (granted the usb one works on the current build)

Otherwise youre left over with a virtual nic and thats pain on unraid, unless you get static ips.

I have a new ethernet interface configured on Unraid and its already connected to the new port on the firewall, both the new unraid interface ant he firewall interface are configured on the new subnet i have built for this and have configured PFsense to handle the DHCP, granted PFsense interface and Unraid interface are statically assigned, I can ping between the firewall and unraid on the new subnet. The only thing I'm missing is a new Bridge Network to attach the new eth1 to that will allow multiple VM's to connect, i need to determine the method for creating a new "br1" interface on Unraid, from what ive found the only way is via CLI, but all of the information ive found seems to be missing pieces and doesnt give me a clear picture.

if youre already that far, you should have the option to create a bridge by simply going to Settings/NetworkSettings.

Been in the network settings menu, before and after, turning docker service off and VM service off, and do not see any option for adding a new BR interface. I only see interface configuration and the ability to create routes, to existing interfaces.

your nic, which i assume is in this case eth1 should show up there and then youll have this option there



that turns eth1 into br1



this is how its looking for me right now

Oh Geez....That was an easy fix, didnt realize that function created the br. It appeared when i looked in that, that it just linked existing interfaces. Thank you alot for the assistance.

you can link multiple nics together so that a vm on eth0 can talk to a container on eth1 but you can also just run 1 nic as bridge so they, docker and vms, can talk with each other.

Glad i could help
