Can you use use the Eero-Gateway as DNS server? Works intermediately? (Eero Plus)
I am using Eero-Plus and know everything DNS wise is transparently redirected to Zscaler services.
So instead of using any ISP or custom DNS, I just want to point my DHCP clients and other clients on my network to the Eero gateway (in my case 172.16.1.1). As any other value would be ambiguities and confusing (my opinion), as zscaler will be used in any case.
I switched all eero-plus features off, added as "custom dns server" the IP of the Eero-gateway (172.16.1.1), and re-enabled all Eero-plus services.
And it seems to work. DNS is used directly. But from time to time, the Eero DNS service seems to quit and fails to answer on the gateway-address (servfails as results). However, the transparent-DNS feature still works (doing a dig or nslookup to a fake IPv4 address DNS server provides answers via zscaler).
After restarting the Eero network, everything works again.
My question is if this setup is supported or not, and I am maybe doing something that is not intended. If it should work, and is supported, I will file a bug or feature request to have DHCP hand-out the IP of the eero-gateway as DNS server as a supported feature.
