Setup
EOS with KDE
home network Mikrotik DHCP network @ 192.168.88.1/24 (network 192.168.88.0) - its default network config on mikrotik devices
On the modem there is pihole in container at 172.17.0.0 network setup with this https://help.mikrotik.com/docs/display/ROS/Container
my laptop have only wifi card
All other devides either directly connected via wire or wireless have no problem accesing net through pihole DNS but on laptop i got limited connectivity error. I can ping anything in 192.168.88.x network, but cant go outside. Other laptop with Win11 onboard works the same with phones.
When i add “other dns server” in KDE connections like 8.8.8.8 or 1.1.1.1 and reconnect all work normally then but pihole is omited in connections now ;/

not using UFW @ home
there was instance of docker running on the homelab server - it was bridged to the same subnet and also in 172.17.x.x range changed pihole to 172.30.0.2 fixed everything
