Hi List,
Problem: . I'm building a PHP application that needs to be able to push requests to an application that is running on multiple computers all sitting behind a firewall. Concept: . I do not have port 80 forwarded to any computer on my router. . Me and my friend can both load up google.com at the same time on the same Internet connection, making requests on port 80. Data is sent from Google specifically to our browser tabs. It doesn't matter that port 80 isn't forwarded, the data from google.com comes back over port 80 specifically to our computers and applications. Can I use this same concept to build a bi-directional communication model for my application? How do applications like Firefox work with making requests that get back through the firewall? What about computer games like Quake? I can hop into a game of Quake with no ports forwarded, yet I am able to send and receive data to the game server without any problem. I need a better fundamental networking knowledge in order to tackle this challenge. I'd love any advice you guys could share. Thanks!
