I see the same issues as Správné nastavení DNS a nepřipojení některých zařízení
with latest Turris 4 RC on MOX
I can easily reproduce this when moving between 2 MOXes 5g wlan with an android phone.
(It connects to first WLAN OK(router with WAN), then you move to other MOX and then back and the phone is effectively DNS confused )
Note that with stable OpenWRT on an old TP-link WDR4300 router this doesn’t happen, so it seems knot or resolver are the prob.
(I am seriously tempted to use the same config with just dnsmasq as DNS+DHCP - is there a safe howto how I can just use dnsmasq on latest Turris for DNS without knot and resolver? I don’t mind dnssec for now (if it helps figuring out a problem either in knot or resolver OR ruling it out of the troubleshooting game completely). )
Any hints would be helpful
