    I had used kids mode/restricted clients mode for some time and it worked, then after upgrading to some Diversion version (5.1 probably?) all my dhcp clients just stopped working, I had to uninstall diversion to fix things, then I pinpointed the problem to the kids mode. As you can see in the...

    Any way to diagnose further these dnsmasq restart events?

    Hello, Last week, I had a trouble with dnsmasq that was restarting so often that I was unable to even have Internet access because I wasn't able to have DNS resolution. I disabled AdGuardHome because I thought it was related (a lot of AdGuardHome's event was registered when dnsmasq was...

    How to make dnsmasq startup wait for USB mount?

    I run dnsmasq on my DSL-AC68U (running the Gnuton variant) with a large blacklist file that is on a USB memory stick. A recent (fairly short, half a minute or so) power failure seems to have provoked an odd problem with dnsmasq failing to see when the USB mounts after power up, but when I did...

    RT-AX86U - Dnsmasq stops resolving DNS addresses

    Hi All, For some time now once or twice a week my RT-AX86U with up-to-date stock firmware (3.0.0.4.388_22525) will stop resolving DNS. All active connections will continue to work but if I want to connect to a new location DNS won't resolve to an address. I have traced the issue to Dnsmasq and...

    Repeater mode + DNS

    Hi, After many attempts, I concluded that probably the nature of repeater mode doesn't allow to set custom DNS on Asus Merlin, perhaps I'm wrong and you guys can give me some hand/workaround. This is my last try. Goal: Set DNS for NEXTDNS / Also their install script does not work on repeater...

    Solved How to check the DNS IP address pushed by the OpenVPN?

    I'm writing a custom script about running a second instance of dnsmasq, and I want the second instance to use the default DNS server provided by the OVPN client, but because OVPN provider assigns a new DNS IP address every time it starts up, So I'm wondering where I can check that IP address...

    Diversion Diversion (not) blocking local domains

    I have noticed some peculiar behaviour which (due to lack of knowledge probably) I wasn't able to explain. While trying to find a problem with dnsmasq's DNS query replies for local domain names (separate story), I was using Diversion to follow the dnsmasq.log with filtering to client's IP...

    Hi, encountering really odd DNS issue after dirty-installing 386.9 fw (upgrade from 386.7-2). On the previous versions of firmware, I was using /jffs/configs/dnsmasq.conf.add for local network name resolution in the form of address=/[server.domain]/[ip]. The domain itself is .home, so...

    Is there a way to set DNS-server priority in Dnsmasq when using DoT?!

    I have setup the two NextDNS servers under WAN with DNS-over-TLS. If looking at "/etc/resolv.conf" it now points to localhost with the entry "nameserver 127.0.0.1". All good so far and it seems to be using Round Robin. I then tried adding these two lines in "dnsmasq.postconf" and with the...
