Endpoint and routing

Hi, I’m using Bluerov2 and i try to use endpoint and route.

So I Connect a serial device on usb port of the raspberry PI companion.
I check the comunication with my serial device with raspberry pi minicom and it work’s on the both direction.

I tried to communicate with the routing system.
So I made route from my serial device to an UDP port 1240 and I recieve all messages from my serial device in my computer.
Now I try to make a route from my computer to my serial device but it didn’t work.
What I miss?
Thank you
