Re: CloudFoundry PCI-DSS compliance issue?

Hi,

iptables is used when Container Networking is *not* available. If you're
using Container Networking, you might want to ask the folks that are
writing it on cloudfoundry.slack.com in the #container-networking channel.

Hi Daniel,

Application Security Groups are implemented via iptables on the host Cell
VMs, and not in the containers.

How does the scenario I've mentioned for AppA and AppB to work even if I
enable AppA and AppB to communicate via http://docs.cloudfoundry.org/
devguide/deploy-apps/cf-networking.html? If iptables is used, I suppose
filtering between VM's NIC and VLAN NIC created by CF inside the VM?

Because if iptables rules applied at VM level's intranet IP, then
filtering rules would have affected other apps on the same VM? Or it works
in some other different way?
