Redirect all incoming traffic from port 80 to Web
I have a project in my Univ. It's a chat App (android). So in order to make the connection is anonymous(future work). I will try connect to my sever first (Digital Ocean) through port 80 then I would like to redirect all of incoming traffic from that(port 80) to URL ( in this case I use Firebase for make communication with my app).
So in my App codes, there is a script that have function to connect my app to Firebase:
Firebase ref = new Firebase("https://<YOUR-FIREBASE-APP>.firebaseio.com");
I change it to http://iup2013.ddns.net . So it's like my App connect to Firebase directly but actually through my server in Digital Ocean first.
Is there any chance about to redirect all of traffic from port 80 to Firebase Url with iptables ?
*why I must connect to my server (digital ocean) first? becasue in future work I will make all of outcoming traffic through Tor to enhancing the privacy.
hope you will help :)
