I am using iOS and android Dig apps. When I enabled proxy-dnssec I was able to get the AD flag on the apps.

Do you mind me asking which apps? I can't get the AD flag on my Android device but can on iOS, but would appreciate a recommendation for both.

iOS - ISC Dig
Android - DNSDig
 
From the man page of Dnsmasq:
--proxy-dnssec
Copy the DNSSEC Authenticated Data bit from upstream servers to downstream clients and cache it. This is an alternative to having dnsmasq validate DNSSEC, but it depends on the security of the network between dnsmasq and the upstream servers, and the trustworthiness of the upstream servers.

Thanks - that's what I'm using as well. I'd hoped it might be a problem with the Android app I was using but that was wishful thinking. I can't get the AD flag to show on Android, will do some more testing.

Are you using Android 9 with built-in DNS privacy, bypassing your router?

So in fact they compliment each other?

Think bbunge’s give the answer. Assuming we trust those big players like cloudflare, Google etc, having both dot and dnssec will be pretty safe from dns hijacking. Unless your clients (pc, web browser, router) is compromised, then that’s different story.

QUOTE="bbunge, post: 460367, member: 30783"]I am using iOS and android Dig apps. When I enabled proxy-dnssec I was able to get the AD flag on the apps. Yes, there are a lot of opinions on DoT/DoH and DNSSEC. There is a link in a prior post that has a good article on the topic

Thanks - I am using Android 9, and hadn't checked (doh!) but no, DNS privacy is not enabled. Checking 1.1.1.1/help on the phone says I'm connecting to CF using DOT. Moreover following the Diversion log shows queries triggered by the phone, including the A record I'm querying to test DNSSEC. So it would appear to be using dnsmasq on the router to resolve DNS queries and Stubby would appear to be working, it's just not returning the AD flag when I use the DNSdig app, setting the router's IP as the resolver.

Using either Powershell "resolve-dnsname -dnssecok" or Bind Tools for Windows, or the ICS Dig app on iOS, seem to indicate those clients are receiving the AD flag. Just not Android (or at least not the DNSdig app).

I'm currently charging up a different Android device to see if it's something to do with Pie. However I've always been suspicious that Android does something a bit funky with DNS, I know my DNS can leak to my mobile carrier over IPv6 with some VPN client configs I've tried.

Update: Nope, same on Oreo. Also tried 2 other Android apps. I can live without it but it's an annoyance to not know why it's not working.

Sorry for replying to my own post, but... installed Termux on my phone and installed the dnsutils package, then tried dig from a terminal window and got the AD flag. Not quite sure what's going on with those DNS apps, there doesn't seem to be any way in the gui for the equivalent of dig's "+dnssec" parameter, but perhaps I'm just using them incorrectly. DNSdig shows a greyed out AD flag so I assumed it would check dnssec automatically. (On iOS the app is from ISC so I guess it's to be expected it checks dnssec by default.)

This is why we should only ever trust the command line. ;)

I've pushed an update for IPv6 users. This update implements the suggestions by @cmkelley in this post.

Note; These changes I am unable to personally test due to IPv6 being unsupported by my ISP, so feedback is appreciated!

Thanks for this. I didn't realize there was a flag for ipv6_service. Makes sense to only put the IPv6 stuff in if that's enabled.

Also, is there a way to have it re-run the install script after it updates the install script?

Its on the todo list, best to make sure everything works manually before automating it. Things have been progressing rapidly so this will happen sooner then later.

Eeeep. I'm dangerous .... In the update_wan_and_resolv_settings section, once you've tested for ipv6 being enabled, looks like you should add:
Code: 
nvram set ipv6_dnsenable="0"
nvram set ipv61_dnsenable="0"
I wasn't thinking about the case where people had enabled connect to (ipv6) server automatically. Ooopsie.

I just updated the installer, and it hangs when I attempt to Update Stubby Configuration (option 1).
 
Does it get through any of it? What's the last message? (it works for me)

Does "opkg update" work when manually run? If not that indicates a problem with entware in general.
