Hello,
First I would like to congratualte you for the development of nwdiag module which is perfect to draw infrastructure network diagram.
However I am still lokking for a tool to produce network flows diagram between components or server. Please below find a perfect example from the VMware documentation.
Horizon 7 Network Ports 2 - Internal Connection Showing All Display Protocols.png (13725×9588) (vmware.com)
It does not seems possible to draw such diagram with nwdiag, does it ?
Regards,
