Hmm, I picked B: Add tcp: ['8883'] in the package_config.ini. But now I'm second-guessing.

Interesting. I think A: Insert in IOS config a static NAT rule might be the right one. NAT issues, you know?

I went with D: Insert in the package.yaml file under section ports: tcp: ['1883']. I thought it was a port issue.
