IPv6 and Android Google play store updates on a Samsung.

[NetworkNitwit]

Not long configured my first proxmox opnsense firewall router(newbie). Using v25.7.x and its been working well. Last night I noticed my Samsung phone had 20 odd apps that needed to updated ,bit surprised ,so I tried & they all kept failing with pending...timeout.

After a lot of wailing and gnashing of teeth I gave the samsung a static IPv4 with DNS 8.8.8.8 and updates started to work.
So google told me its a IPV6 issue and I turned it off on the interaces and put the samsung back on DHCP and yes it works.
Now I dont really know why but I would like IPV6 working maybe its the future!

I'm using .internal as my domain is this ok & how can I see where its falling down when I try to update apps? I looked in firewall logs and couldn't see an issue, during the process I turned off my firewall & IPS completely.

I'm using DNSmasq and Unbound as OPNsense documentation suggests for default install 2026. Any pointers to other logs which could highlight a DNS/DHCP issue I would be appreciative.

This part caught my attention :

Usually Android phones (sadly and annoyingly) use both 8.8.8.8 and 8.8.4.4 by default as their DNS and you have to put 2 or more DNS Servers in your DHCP settings in order to "overwrite" that behaviour !!

So it's really interesting that one of the worst of them all (Samsung) does not seem to do that (anymore ?!) and now I am very curious which phone you have exactly and what Android/Software version it's running ?!
