Hi,
I recently bought the Netguard pro functionality.
Read that i need to use the github version to use the host file option, so i installed that version.

I own a Xiaomi Pocophone F1 phone, and now manually disabled some servers and apps.

I found a xda topic to use a blocklist with adaware.

https://xdaforums.com/redmi-note-3/how-to/adaway-blocking-miui-calling-home-t3516119

Is there a way i can import these in Netguard easily?
Are these entries in the same format as in a hosts file?

Probably a nooby question, that someone here van help me without. :confused:

You can import (additional) hosts files in the NetGuard backup settings.

Yes!, great news, thanks for sharing Marcel.

It looks like a new API called getConnectionOwnerUid will be added as an alternative to using /proc/net (this is the corresponding review), which won't be possible anymore on Android Q. I really hope this won't be revoked and that it will work properly and fast enough.

Edit: I have checked the Android source code and this solution should be more accurate and faster than the current NetGuard implementation, so this is really good news.

If you didn't already and are able to, please star this issue to increase the chance this will be in Android Q.

all connections blocked only by netguard

All connections blocked is a known problem for LineageOS on some devices. If you hadn't related blocking all to the Android always-on VPN, I had told you that right away ...

Now it got me too.
After updating my Samsung Note3 (hlte) to LinageOS 15.1, NetGuard blocks all connections when it is activated.
That lies however, according to my understanding, probably not basically at LineageOS 15.1, because Blokada and DNS66 VPNs work without this blockade.
How can I use NetGuard with LineageOS 15.1 on my Note 3 again?
This error with Lineage OS 15.1 and later should also be found in the description of NetGuard if it can not be fixed.

Everybody always says it is NetGuard, but it really isn't.

Intercepting DNS only is something else than intercepting all traffic

It is not an error that occurs with LineageOS, but only from LineageOS 15.1 and affects NetGuard, not e.g. Blokada and DNS66. With LineageOS 14.1, NetGuard ran smoothly on my Note 3.
I have also tested the "NoRootFirewall". Runs easily on the same device. In this app can also be blocked only individual apps.

It is a problem with klte and bacon devices (and maybe others) on LineageOS 15.1 and 16.0. Things were cool on 14.1. If you are running official, log a bug https://wiki.lineageos.org/bugreport-howto.html I'm running unofficial so cannot.

Still it is a bug in your LineageOS variant/version. NetGuard does not route traffic in the same way as the other apps. That it works on another version of LineageOS should be proof enough.

There will be no official for note 3, so I am also on "unofficial".

Too bad, always the same answer to read ... unfortunately no solutions. LineageOS 15.1 and higher will work with other no-root firewalls, so of course there will be no solution to a problem with NetGuard from there. What a pity...

Maybe you are smarter than me and you can fix it. The source code of NetGuard is available on GitHub.

Well contact the place you downloaded it from and see if the dev is smart enough to fix it. I think its a kernel problem with msm8974. Either way it's not Marcel's problem, leave him alone! ;)

No, I'm certainly not smarter, but I'm just trying to get at it with my simple logic. If other no root firewalls (even really old apps) can do that, why not NetGuard.
But I see, I can not get on with this logic ...

Like I said, not all VPN apps route traffic in the same way.

For example: does any of the other apps have an option to allow LAN traffic? No, they don't.

I remember having read about issues with Samsung devices ever since I am using Netguard (long time). Lineage OS 16 (unofficial) is compatible with Netguard on my Moto G6+. Lucky me...

Hello,

Today my phone (Motorola G5S Plus) received an OTA which upgraded it from Android 7.1.1 to 8.1.0. From that moment NetGuard blocked all traffic.
After reading in this thread and the Netguard FAQ, I still haven't found how to get NetGuard working the way it did with Android 7.1.1.
...

For those who are affected by the same problem: for the Moto G5S Plus the problem was solved after receiving the February 2019 update.
This means that not only NetGuard is working again, but also VPN in general..

A question about interpreting a notification.

This on a new unrooted phone using android pie. Github NetGuard pro installed, host file downloaded and installed.
Attached is the screenshot I have an interpretation question.

1. If internet and data access is denied in NetGuard does this mean that the 'access attempts' marked in red went into the vpn and thus nowhere?

Or do I need to do something else to block them?

2. If some are not red, can I block them from the 'access attempts' screen?

Thank you.

The traffic was blocked and is going nowhere.

You can tap on an address to block or allow it.
