cannot resolve 'TCP port numbers reused'

[Pascal]

Hi all

I am trying to set up a number of nodes that send TCP packets to a number of different targets in an alternating manner. The simulation itself executes fine, but when I look at the pcaps, then the TCP handshake only completes for one of the target node connections per sender node.

I have simplified the example down to 3 nodes: 1 sending and 2 receiving, but the problem persists and I can't seem to figure out how to fix it (by e.g., changing the port numbers during configuration of the sink addresses).

I have attached the pcap files and the script so you can get the full picture or try and reproduce the results. (handshake fails in 'alternating_traffic-2-0.pcap').

Any help is much appreciated, thanks in advance,

Pascal

I feel silly now. Thanks for your help Tommaso, much appreciated.

It happens, that's why one should always check for errors after a good sleep.
