<div dir="ltr">Hi Jelena,<div><br></div><div>I'm using similar setup with 4 bridges (actually 5 including the lxcbr0 that lxc creates for DHCP/NAT) on Ubuntu with no problems. Could it be that you are accidentally reusing MAC in the lxc guest config of the new guests?</div>

I wont to create for example two virtual interfaces in container and each of them to connect to different bridge.

<br></div><div>First I started with two containers (container1-bridge-container2).

<br></div><div>Then I wonted to connect one more container (container1-bridge1-container2-bridge2-container3). Created one more interface in config file in container2, and one in container3.

<br></div><span lang="en"><span>I checked</span> <span>every config file</span> <span>several</span> <span>times, bridges too but i couldn't find problem. </span></span><br>
