I try tu use a second nic for one docker and it is not working.

 

I did an interface in the docker network

When i try to assign an IP in the docker setting

 

 

root@SERVER-DAN:~# docker network inspect iot
[
    {

I don't think you can do that.

What's your goal?

what's your network(s) ?

if your Unraid network is 192.168.1.0/24 the bridge can't be the same network.

you can create a sub interface on a vlan and create a macvlan network with the sub interface as parent.

or you can add a second Nic in another network and create a bridge network on that Nic. 

You can also create a macvlan network on the Unraid host network but you need to pay attention to not overlap DHCP range.

But 2 Nics in the same network on the same host don't play well.
