What is the Relationship Among Different Versions of Softwares?

Installing and Using OpenWrt
37

Hi, mbo2o:

  1. Great! Let's work together to either prove or disprove the idea.

  2. To expedite the progress, allow me to recommend a couple general guidelines:

A. Let's contribute what each of us know and capable of when requested. (I follow an almost contradicting philosophy. That is, I know that I know enough of certain topics, so that I am not shy about admitting that I do not know some topics.)

B. Respect the other's approach / opinion. Raise comments only for the purpose of understanding it, not to critique. (In the process of clarifying, the other party learns how to convey his idea better in future presentations.)

  1. Appreciate your preceding interesting comments that do have certain amount of truth in it. Let's put them in the background for now, except I should address "untold wealth ":

It is too early to dream about this possibility. On the other hand, I have taken appropriate steps to be sure that it will not be totally thrown away. I can only promise that when reward does shows up at the door, each and every contributor will get respective fair share from it.

  1. While I will be continuing my study of OpenWrt documentation and learn from the manufacturers, there were two initial questions cut short by the SysAdmin because the discussions went off track. I would like to ask again for possible confirmation which will expedite my learning curve.

A. There were lists in two Topics (see below) on this Forum that mentioned the 240/4 netblock. Each also included the common private 10/8, 172.16/12, 192.168/16 plus others. My question is, does this mean the 240/4 is inherently included in the OpenWrt routable table, or can easily be set up under OpenWrt? And, where can either be confirmed in the OpenWrt documents?

B. There were a couple initial tests conducted by colleagues (see below) with apparently contradicting results that the specifics were completely out of my league. I was hoping to see some definitive result with finite steps that could guide me to replicate.

Can OpenWrt Route 240.0.0.0/4?
Can OpenWrt Route 240.0.0.0/4?

Thanks.
