Port forwarding on Spinnaker

Question

I am doing a port forwarding to connect my local machine to Spinnaker.

Step1: -> Localhost to AWS instance

ssh -A -L 9000:localhost:9000 -L 8084:localhost:8084 -L 8087:localhost:8087 ec2-user@<aws-instance-ip>

Step2: -> Aws instance to Spinnaker cluster

ssh -L 9000:localhost:9000 -L 8084:localhost:8084 -L 8087:localhost:8087 ubuntu@10.100.10.5

This works fine when i do http://localhost:9000

However, instead of port forwarding from local machine I want to setup a tunnel from another aws instance (Eg: 55.55.55.55) and access via http://55.55.55.55:9000 . So that other team members can i directly access Spinnaker UI.

I have tried following the above steps from 55.55.55.55 host and then tried

http://55.55.55.55:9000 however it didnt work. 

What should i change to make it resolve on 55.55.55.55 host?

Port forwarding is bound to the IP you give to ssh. If you give localhost (default), it will be accessible only on localhost (127.0.0.1). If you want to access it from outside, you need to give the 55.55.55.55 address instead.

You will also need a -g switch to ssh, which will allow remote hosts to connect to your locally forwarded ports.
