Hi, first of all sorry if my English is not so good. I want to offer a service to some clients and want to creat a network to make it work and make it safe.
I’m not a network expert at all, but I think I can understand a few things. So far this is what I have done:
This can work, but I want to make something more safe, and learn during the process as well. What I’m trying to achieve is this:
Now, I know there might be some things that are in a higher difficulty level of what I might understand, but I can figure it out if some one is willing to help me 
I think everything can be done based on what I have learned so far, but can’t figure out how to do it myself.
If I need to reset all configuration and start from 0, I have no problem with that, I preferred it that way in case something is misconfigured.
If there is any other information needed please let me know.
Thanks in advance.
