Firewall container

Hello guys,
i’m doing a master thesis and some research using containers, in this case, docker.
Did you already used docker to virtualize firewall applications?
Some best practice or article will be grateful.
thanks!

Well iptables is a FW. A few seem to exist on the docker hub, and example:
