Ubuntu, LXD and masquerade

sorry simos for my english - maybe that is problem.

Try to explain:
When create Virtual Machine on VMware, XEN, FreeBSD Jail, etc. you can attribute IP (public or LAN) for this VM.
All Incoming/Outgoing package have this IP.

It is possible to do this with LXD?
iptables can do this - Prerouting and Postrouting.
But MASQUARADE on first place destroy everything.

Example: if we have Host with 24 Container and all of this Container go to Router with the same IP address from Host. Masquerade do this.

It is possible to create LXD container with dedicated in/out IP address?
