ANDROID NOROOT FIREWALL

December 17, 2020

Hello everyone and today i wanna share with y'all an application for android which of have firewall functions which i found and have to use.

I've got dream about somethin' like that a lot of time, and i finally got it!
Here i leave the link for play market version and my video with screenshots in the footer of page, and now i gonna describe the functional.

So firstly as u can see, the application isn't require root access, and that's very good for u, if u've a new device with android 10 version and theres no way to get root access and unlock bootloader.

The advantages of application is that u can route traffic of ur applications, block traffic from an applications which is u choose and allow it to another. By defauld all traffic is blocked and firewall ask u for further action.

Also, u can block traffic by port. For example i've cut off all traffic at 80 port bcz there's goin' pages without any certificate. But u'd remember, that all updates might goin' throught 80 port, so don't forget about it.

Also, u can block ur traffic for an mobile network and allow it only at Wi-Fi connection.

And that's still not all!
Here's u can have somethin' like simply DPI or Layer 7 and just put a DNS name of the page for block it. For example, u can put yandex.ru in the address, highlight 443 port and all packages with this DNS name will be blocked. Of course u can try to block it by IP address of the server but, pages usin' a lot of servers and maybe u can't block ur page by only IP address.
