[athul-am]

Hi all,
I have a scenario where i am using a board that has 4 ethernet ports. I would like to create 4 Applications or Instances where each one is listening on each port is this possible? if so how?

The other 2 situations are I need to send the Service Discovery using Unicast and the the Subscription port of my client i need to keep that from the someip config .Please let me know if anyone has done this . It would be a great help!!!

Thanks,
Athul
