Single channel packet forwarder not sending data to the gateway bridge

Hello, I am using a single channel packet forwarder, I set up the server correctly and I can acess the web interface. The problem is that i can’t reveice any data.
After using the following command, I discovered that the packet forwarder is not sending data correctly to the gateway bridge:

this is the packet forwarder which means that the gateway is receiving packets from the node

and this is the gw bridge running

You already posted this question in which is the same issue and is independent from single / multi-channel gateways.
