I would like to do a small experiment to modify received packages and send them back. I would like to do a small experiment to modify received packages and send them back. And when I tried to run test-tcp.click in my topology, an error occurred like this, 'out :: SetTCPChecksum' push output 0 connected to 'SetIPChecksum@16 :: SetIPChecksum' pull input 0 Router could not be initialized!

How can I fix the problem?

This seems to be a problem:

'out :: SetTCPChecksum' push output 0 connected to 'SetIPChecksum@16 :: SetIPChecksum' pull input 0

This implies that a push port is connected with a pull port which is not allowed!

You can try to introduce enqueue and dequeue elements in between them for proper processing.

Best regards, Sumit
