I have a webapp that I'm testing via SSH; it's available on localhost:webappport when I'm logged into the pi. However, if I try to view the webapp by going to the pi.ip:webappport from another machine on my local network, I don't get any response.
Now, I assume this is because the pi is only making the webapp available to local resources - so how do I make the localhost traffic accessible to an external connection? I'd be happy to do this with a simple web server, or with some sort of SSH-hosted connection. Ideally, I'd like it to be a simple / straight forward process that's not terribly insecure. (While I'm only using this to test locally right now, the option to reapply what I learn here to future testing, including that not limited to the LAN would be quite helpful.)
So, what's the best way to serve localhost traffic to a direct connection (via IP) on my local network?
