How to allow the entire network traffic via proxy port by not filtering via certain urls?

[ezhiljohnson7]

Is there a way I can channel my entire network traffic via toxy, just like the way we do it with tools like charles? Currently, I'm able to forward traffic from certain URL's via toxy and apply poisons to it, but don't see the whole network traffic going through the proxy server that I've opened in port 3000 despite adding "proxy.all('/*')". If I have an android device connected (with manual proxy in the Wi-Fi settings) to the proxy server running in my computer on port 3000, the network connection is not established and no sites are accessible.
