plantuml doesnot create network diagram when there are more than 3 networks and few nodes share it

Question

Below is my code.

 I need web01 and web02 to be connected to internal2 network along with dmz and internal. Executing this code doesnot generate the required diagram(web01 and web02 are only connected  to dmz and internal in the diagram generated)

@startuml
nwdiag {
  // define group at outside network definitions
  group {
    color = "#FF7777";

    web01;
    web02;
    db01;
  }

  network dmz {
    web01;
    web02;
  }
  network internal {
    web01;
    web02;
    db01;
  }

  network internal2 {
    web01;
    web02;
    db01;
  }

}

I'm curious as to how you would expect this to display.  I mean, do you envisage two 'web01' boxes, or would you expect three lines coming out of the 'web01' box one of which would have to cross over a rail?

Hello S. and PlantUML team,

On Plantuml, that is KO (internal2 is not good):

But if you go directly to the site of the nwdiag's author, that is OK, we see all the 3 networks (and the internal2 is good), [copy/paste your code without @startuml/@enduml on]:

Maybe PlantUML should update to the latest version of nwdiag...

On the same suject (nwdiag), the "peer networks" is broken (We does not observe the cloud on the PlantUML version), see the differences between:

1. the PlantUML doc: https://plantuml.com/nwdiag#44fc6e53afc4fcef
2. and the nwdiag doc: http://blockdiag.com/en/nwdiag/nwdiag-examples.html#peer-networks

If that can help,
Regards,
Th.

This is awesome. Thanks. The-Lu

Few observations:

1)What is the vertical line going up in "dmz" network

2)I would like dmz line is also same length as internal and internal2.

Hello A.,

1)What is the vertical line going up in "dmz" network

1) This line going up in "dmz" network seems to be the link to outside or to a router of an external network, like the Internet.

If we see all the examples on the doc. page (http://blockdiag.com/en/nwdiag/nwdiag-examples.html), all of them have it!

2)I would like dmz line is also same length as internal and internal2.

2) Perhaps you can ask a new feature directly to the author of nwdiag, on:

• https://github.com/blockdiag/blockdiag/issues
• https://groups.google.com/forum/#!forum/blockdiag-discuss

If that can help,
Regards,
Th.

Thanks a lot for the answers

Hello all,

FYI, with the last version V1.2020.16 (23 Aug, 2020) of Plantuml, that is now OK (internal2 is now good: web01, web02 and db01 are now on internal2):
