I have a server on an internal network that publishes web pages. I need access to these web pages from random clients on the Internet. The problem is that I don't have control of the firewall this server is behind. On the other hand, I do have access to a public server on an entirely different network. (OSes are flexible: I have access to both Windows and Linux servers on both sides.)
Here's what I'm sort of looking to do:
- Client hits a port on my public server.
- That port is forwarded (tunneled?) to the internal network.
- Web page is served back to the client.
SSH tunneling doesn't seem quite right. Would a site-to-site VPN could do the trick? Is there a simpler option?
