Hi Ron, It would be helpful for all the users in the community if you can specify what changes needs to be done for the cloudstack documents to get way with the confusions about the networking. If you specify what problems you have faced while setting up the cloudstack that would also be helpful.

There are still 3 consecutively numbered C class registered to me for different clients back in the days when c-class networks were given out from massive ranges of free numbers. I have set up small ISP operations for clients with multiple domains including web sites, e-mail servers, fileservers, etc. I have done this on SCO , Mandrake, CentOS 4 to 7. I should not have to struggle to figure out how set up Cloudstack in a small configuration with a few servers and a single public IP. The documentation on networking is jumbled about and so unclear that I can only point out why it is not clear but can not figure out the truth sufficiently well to actually fix it. I still don't know where the sources for the drawings are kept even though I have asked several times. It needs a team approach with someone who knows the truth and someone who can write it down so that someone who did not write the code can figure out what to do. The biggest problem with programmers writing the user documentation is that they are so caught up in the exceptions and special cases. They spent a lot of time figuring out how to handle these oddball cases that they feel that these triumphs must be on the front page. They forget to explain the 95% case and lace the description of the main flow with notes about these interesting exceptions. That is not just true for Cloudstack but is a general problem with documentation just because we are all human. They also forget that the user does not want to be an expert in the topic but wants to know enough to get the thing running. The user has a lot of other problems and does not to become a developer in order to get this to work. In my case, I really need to get some internal applications (accounting, SCM, issue tracking, Maven repo, 20 web sites etc.) running on virtual machines in an environment that is easy to manage. I want to support clients who I am supporting as users of other systems - just want simple low volume services to support my supporting of their users. I only expect to have 4 servers, one NIC per machine to support 1 transaction per second on a busy day I may get down to 2 servers if Cloudstack works well and allows me to manage test servers and run docker nicely. I do not want to know enough to be the network administrator at Google or Amazon. This should not be hard to implement and from what I have seen it is not but the networking docs are a major barrier to acceptance by mid-market companies - 300-1000 users with 1 or 2 System Admins who have to support all of the operations requirements and help developers and application support teams test and keep production systems running.
