HTTP hole punching - Web server behind NAT

1
votes

I have some Raspberry Pi servers behind NATs (non configurable, ISP provided), on dynamic IPs, and a "master" server with static IP and port forwarding configured on the router. I want to be able to access the page served by any of those RPi servers from any browser. I've read about TCP hole punching, but I can't figure out how to make it work from a browser (I guess using AJAX). I could use the "master" server as a relay server, but don't know how to. BTW, all traffic to/from the servers use HTTPS, not HTTP.

EDIT: The Raspberries and the server are NOT on the same network.

You might investigate the use of a reverse proxy (I've used NGINX). A reverse proxy allows traffic to hit your server with the static IP, and forward HTTP traffic to other servers behind the firewall.

It gets a little more tricky with HTTPS, but it can be worked out.
