Recent reviews

Worked great originally, but latest update (0.56) broke local connections. Everything comes from 10.111.222/24 now, so local things that previously allowed my phone IP no longer do. Gave up trying to debug and just went back to 0.55u, which works fine. I know there's option to disable for local addresses, but the entire point is I want the firewall applied to everything. I don't want it changing source IP.

i'm trying to use this app to stop ads like on MX Player by stopping the internet/data connection for that app. but it is the same as NetGuard or similar apps. i can somehow stop it but the ads will be shown as blank ads. just a pop-up without any image nor video. but blank ads can have waiting time too. and if you clicked accidentally the ad area, you will still get redirected to some ad sites. the only thing that it can stop is the ads blocking the screen when you pause the player.
