I had similar issues with multiple TCP ports.  
In the past it seemed fixed:

But most recently i have started using virtual com software, which makes the code less hard to duplicate when switching ipadresses.

If you are running linux you could use socat. [https://www.redhat.com/sysadmin/getting-started-socat](https://www.redhat.com/sysadmin/getting-started-socat)

On windows you couls use USR vcom or Lantronix CPR
