I was giving a transparent firewall a try, and wondered whether cake can be applied on the interfaces of a bridge. I want to put an extra router in-line between clients and the ISP-modem-router. It will have two interfaces (eth0 facing wan, eth1 facing lan), bridged together as br0. 

Can I fearlessly apply cake on eth0 and eth1? Would this be compatible with features like ingress, ack-filter or even nat?
