I'm playing around with the tcp-routing feature in the latest Lattice release. I started two node.js applications in the pushed image (listening on two ports), one mapped to an http route and the other to a tcp route. I can connect to the http route successfully in the browser, but when I try to connect to the tcp port in the browser, I got connection refused. It looks like the mapped public tcp port on 192.168.11.11 is not open at all. Any advice on how to diagnose this? Thanks in advance!
