Networking newbie question:
I am trying to understand what would be the best way to expose several mobile web servers, all of them are behind a router which is a typical 3G network configuration, here all 3G mobile has only a private IP, so in this case we have several web servers all of them are unreachable.
If a have a DNS server can I use DNS A record to point to this web servers (no public IP) and a reverse proxy (d.example.com) to forward traffic to each mobile web servers?
The application that I am trying to do will make those web servers accesible (no public IP) using a subdomain of the proxy server for instance 3gwebserver.example.com
Is there a way to accomplish this?
