The scant documentation I can find on running containers only ever speaks of single IP assignment schemes. Can I have for example a box with a single NIC with 8 IPs assigned to it, where the host gets one IP, or perhaps alternately can see all 8 to run iptables across, but each of the containers can see only whichever IP or IPs are assigned to it? If it can work this way, I'd appreciate any hints on the correct way to implement it. If it can't, I apologize for barking up the wrong tree, and will need to look at full virtualization methods which can. Thanks, Whit
