Hello and sorry if this was already sked, I didnt find my case, just something like it.

The purpose of separate VM is to be voip server + stun/turn ( does not work behind NAT with port forwarding ) and with separate channel.
Im trying to make linux bridge to nic2, not setting any ip or gw on bridge interface itself.
Then make vm with virtaual nic in that bridge with right MAC and trying to get dhcp lease with no success.
Setting ip/gw/ns manually does'nt help either. Clearly, i do not fully understand how virtual switch/linux bridge works.
Thank you in advance.

Seems like I made some mistake last time entering manually network credentials. Seems to be working fine just as I described
