I'm a longtime user and supporter of all of Marcel's excellent apps.

I noticed that one of my apps (AnySoftKeyboard) is listed in Netguard in a lighter font in Netguard.

What does that mean? Thank you.

Hello, i hope i'm right here.
In my protocol i saw that my phone send icmp4 pakets to an IP from Port 8000-10744 and net-guard not shows the application its send. It is possible to block that? I own all pro-functions.
Sorry for my terribel english.

This type of traffic can't be forwarded because the Linux kernel doesn't support this, which means that this type of traffic is always blocked.

Hello. What about blocking plain-text http? Everyone uses https these days, but WhatsApp and Telegram do functionally useless outbound http connections. Other apps fall back to http, when https fails (e.g. in case of unstable connectivity), however I'd rather have the connection fail.

Also, what about enabling the GitHub tickets or a dedicated issue tracker? I cannot find how to search in this huge thread, if that's possible at all.

Thank you for this great app!

You can block any connection you want. Falling back to http in case of unstable connections seems nonsense to me. Show me an example.

GitHub issues were disabled after frequent abuse on all my public repositories.

Hello, I wanted to thank you for this essential app! This should be added to the AOSP project. I have a small issue though... I'am using Google MEssages app, connected to chrome on a Windows PC. Whenever I lock the screen, the app can't synchronize until I open the messages app on android. All battery savings are off, always on vpn is enabled. Any idea how to fix this issue? Thank you.

Hello Friend. Thank you for this amazingly blazing fast reply! Indeed this fixed the issue. But I'am not very happy, that the main application I wanted to block needs access to the internet... 😁 Thank you again for the great work and advice! Godspeed.

I'm trying to capture and analyze the packets of a particular app.

My strategy is to block all network access and enable (whitelist) the particular app.
Then I want to capture pcap logs only for apps that are not blocked, but I can't figure out how to do the latter.

Is there a way to log only the allowed traffic to the pcap file?


Another option would be to find a way to determine which packet in the pcap is associated with which app. I know others have asked for this and the pcap file format doesn't support such a thing. But, when your export the pcap file, can you write a second text or csv file that contains the information shown in the log screen (timestamp, app, destination address, etc.)
With both files, I could manually correlate a packet in wireshark to a packet in the text/csv file.

The PCAP file is meant to contain all traffic, and doesn't support extra values, like for example to indicate the related app.

The support for this project is rather limited despite millions of people using the app and Play store reviews are rather often pretty disappointing as well, which is why I will fix important bugs only, and won't add new features anymore.

Dear Friend, don't allow other people to let you down. Few opinions of people who truly understand your work, spent some time to understand it is more valuable than the raging fuss of people who can't invest few hours into understanding the app and always seek instant gratification... There are a lot of people who really appreciate the amazing piece of software your provided. Thank you.

There are always people who install an app but do not understand the app. You shouldn't get upset about these bad reviews.

You have the best ratings in the firewall apps. That has a lot more validity.

It's often a bit of a struggle for me when I have Netguard set too restrictive again. But that's not Netguard's fault. When I see all the traffic, it's just a small restriction.

I'm still hoping for some further development.

Just as sure, I am very uncomfortable without Netguard.

Of course, for each device and for each activated Netguard was donated. This app is worth it to me. Even without further development

The simple fact is that the negative messages I receive daily, more than outweigh the positive ones. If I say negative, that's expressed mildly because it includes harassment, stalking and even death threats.

I released a new version and there were seven thanks. Any idea how much rubbish I received in the same time?

I think most people in the same situation as me would have cancelled the project a long time ago. I don't want to let down loyal users though.

I have no understanding for these annoyances.
Netguard is not compulsorily required or has a monopoly. If someone doesn't want to use Netguard, then let them not use it.
Unfortunately, it is also a reflection of our society.

I will continue to support Netguard.

You certainly know that the haters are much louder. But there is a very large grateful fan base.
