Enhance z/OS IP Filtering so that rules can be defined to control access to ports that containers in zCX are listening on

Currently z/OS IP filtering only allows rules to be defined to control access to the TCPIP address that a zCX Instance uses.

In a zCX instance, we can run a number of docker containers, each listening on different TCPIP Ports.  Each of these containers can be running applications for different business purposes.  

z/OS IP filtering should be enhanced so that rules can be defined to control who can access different TCPIP Ports that are being listened to by the different containers

    We solved the problem with a reverse proxy. This has the advantage, you can also share a port and point to another container depending on the source IP. There is also the possibility to use TCP whitelisting to restrict access to containers.
