I am in the process of building a dial up simulator involving a 1990s era desktop and laptop. The desktop, which is connected to Ethernet, acts as the dial-up server and the laptop computer dials in to the “server” through its built in modem. The connection is made through a Teltone telephone line simulator.
I downloaded a “vintage proxy” from GitHub in which typing in a url (ex:aol.com) will return that page from a year in the past using the Wayback Machine. This proxy will be running on a modern third computer.
My question is how the dial-up connected laptop can access the proxy server on the modern computer through the dial-up. I know that if I use a wireless router, I can access the proxy using the server’s IP address, but I don’t know how to do this through the simulated dial up connection, since the modern computer is connected to wifi, not through the simulated dial up connection.
