Im very very gratefully for your help and your dedicated time to me but i
don;t understand what you mean exaclly. I tried everything from scratch.
Did again from link as i sent, did from tutorials on the internet, did from
forums. People have the sam problem as i have and can't find solutions.
I've been  spending almost the whole day, ehhhh

I only want to have

host on ip: 94.23.237.216
and lxc on ip: 91.121.239.228

Is there other way then bridge (br0) ?
