Hi guys, I'm using a BT Home Hub 5A with OpenWrt 18.06.2 r7676 connected via ethernet to my main ISP router (DGA4132, TIM, Italian ISP).
DGA4132 IP is 192.168.1.1 and I've configured DNS in its webif using Google DNS, so every pc connected to it in DHCP uses Google DNS. BT Home Hub 5A is 188.8.131.52.
Now, when I connect ethernet to BT Home Hub 5A, every computer connected to DGA4132 shows 192.168.1.99 as DNS ipv4 and doesn't use Google DNS anymore.
How can I configure BT Home Hub 5A to fix this situation?
Thanks in advance for the reply!
