Description

I have a tcp-echo server running locally through:
podman run -d --rm --name tcpecho -p 9090:9090 quay.io/skupper/tcp-go-echo

And I have a router configured with a tcpConnector to localhost at port 9090 and a tcpListener at port 9999.

I am able to use nc (netcat) to send data to the tcp-echo directly (port 9090) or through
the router (port 9999), if I run "nc 127.0.0.1 9999" and the send the data.

But if I run it as:  "echo abcd | nc 127.0.0.1 9999" I am not seeing a response, but if 
I use port 9090 (original port) instead of 9999 (router tcpListener), then I get the
response correctly.
