Thanks everyone.

Last question (not sure if it has laready been answered), how can I check if Stubby is really working?

Checking https://www.expressvpn.com/dns-leak-test says that the DNS request is still being exposed.

That test is meant to make you think their service is better. Think of it as false advertising. It does say your DNS may be logged but it does not say if it is being logged. Just that you are not using their service.
One sure way to test is to switch to cloudflare and go to their help page. But the stubby -l will show connections to your DNS

Trying to make one for Arm7. Never compile stuff before.

Inside getdns’s Makefile, there is already
Code: 
CONFIGURE_VARS += LIBBSD_LIBS=-lc
Do we need to remove it or just add on the bottom?

CONFIGURE_VARS += \
    LIBS="-Wl,-Bstatic -lssl -lcrypto -Wl,-Bdynamic -lpthread -lc -lgcc_eh"

Do we need to add anything to stubby’s Makefile?

Hey guys thanks a lot again.

I just saw that since I am using a VPN Client I also need to set “Accept DNS Configuration” for the DNS Client to “Disabled” and also remove the “dhcp-option DNS 80.241.218.68” line in the Custom Config for VPN Client.

Is there anything else I need to change in order to make Stubby work flawless?

Nope that should do it.
 
Stubby's working fine, no noticeable problems so far. Thanks again to @Xentrk and all contributors here.

In the meantime I did a test round with netalyzr. --> http://netalyzr.icsi.berkeley.edu/
As soon as I deactivate Stubby this message no longer appears. So it is reproducible for me.

Everything looks good so far, are on a recurring message:
"Your DNS resolver is unable to receive a large (>1500 byte) DNS response successfully, even though it advertises itself as EDNS-enabled."
Click to expand...

Explanation:
"EDNS and DNSSEC: Extended DNS (EDNS) is an optional mechanism in DNS, commonly used for DNS Security (DNSSEC). This test records whether the resolver will request DNSSEC records and use EDNS to accept larger results."
Click to expand...

Your opinion?

(If you want to test netalyzr yourself: it works either with InternetExplorer 11 or with Firefox 52.1.2 (32bit) with installed Java. Alternatively via netalyzr's Command-Line Client.)

:)

Stubby for me depends on the connection realization provided by my ISP. Make an evaluation of the connection and adapt the stubby.yml.

Should I also change now round_robin_upstreams: 1 to round_robin_upstreams: 0?
Click to expand...
Yes. with only one DNS Upstream Resolver it make no sense to use roundrobin. You do have two entries but they are for the same DNS server. One IPV4 and one IPV6 address.

The idea of using roundrobin is to have some load sharing between two or more DNS servers. With the prior release of GetDNS and Stubby there was a bug that some times would not switch to the next upstream resolver and enabling roundrobin seemed to avert problems. I have been using Stubby with roundrobin disabled since the new release came out with no issues. I do have two IPV4 resolvers configured (Quad9).
 
Hallo,

I am a "noob" user and managed successfully to install stubby via amtm.
What do i need on the client side (Windows 10 PC) to properly use DNS over TLS please ?
Do i just need to set my LAN Adapters to DHCP ?

Thanks in advance,
Ingo

nothing. make sure your pc gets its ip and dns from the asus router.

Thanks. so basically i just set my 1st DNS Server in the ipv4 settings in windows to 192.168..1.1 ?
with "stubby -I" i see the following so i assume it is working:

Installed Stubby via amtm after uninstalling DNSCrypt & rebooting Asus RT-AC86U router. If I turn ON my OpenVPN client (IPVanish) on DNS leak test it's showing my IPVanish DNS. With OpenVPN client OFF it will resolved to Cloudflare (my DNS of choice). Netflix-VPN-Bypass also won't work if OpenVPN client is ON no matter what setting I put in Accept DNS Config or remove the (dhcp-option DNS 1.1.1.1) on Custom Config. No changes made yet on stubby.yml. Any help?

You should be using Accept DNS config=disabled and remove your extra dhcp-option.

I did that. Also changed the DNS server address (router IP) on PC. Now my DNS resolved to Cloudflare on DNS Leak Test. Neflix-VPN-Bypass also works. Passed the DNSSEC Resolver Test. On Cloudflare SNI Checker, Encrypted SNI failed. Used Firefox Nightly with Encrypted SNI enabled. Is there a way to forced other gadgets on network to use Cloudflare DNS without manually changing it on each device?

Let your devices get their IP address and DNS from the router. If you want a consistent IP address on a LAN device use the Manual Assignment in the Asus router. That way all your devices will pass the DNS queries to dnsmasq which passes them off to stubby/getdns which send them to whatever you have configured in stubby.yml. Of course you know that..
I suspect that using a VPN client on a network device could change the device DNS setting. I have tested one of the free VPN services on an iMac and when I successfully connect to the service in another country the Mac system properties shows the DNS servers set to Google. I do not use a VPN client on the router so I can't say what that does but it likely could change the DNS for the VPN connection and your DNS queries could go to ????
As a reminder... the DNSSEC testers on the web just test if your resolvers are capable of DNSSEC. Not that your DNSSEC works. My recommendation to most folks is to not enable DNSSEC in Stubby or Merlin as there is a good chance you could get a failure to connect to the resolvers from time to time.
