So I bought into the EERO way back during the pre-order days. It seemed to be a great solution at the time (there was NO other mesh network options). I was super excited when my 3-pack arrived!
Alas, my excitement was short-lived, as I ran into an incompatibility between the EERO and my cable modem. The version Time Warner was pushing/supporting at the time had a bug that the EERO managed to trigger, causing network drops, lost packets and all around headaches.
So I set them aside….. Until just recently my Asus WiFi router decided to start acting up. Reboot on it’s own and take a while before reconnecting everything. So I did a quick check and hurrah!, Time Warner (now Spectrum) managed to patch my cable modem so it would work with the EERO’s.
So I dug them up and setup them up. I have to say, they are nice and simple to configure…and fast! But, I ran into some immediate problems. Like trying to access *this* blog’s backup site from within my own network. I use the fully qualified domain name, backup.azurenight.com But I can’t reach it from inside? What???? Google Search to the rescue, led me to this: https://community.eero.com/t/q561rb/egress-hairpinning and even though this issue is more than a year old, still no resolution!
I wasn’t about to spend more money to setup an edge router….and I don’t want to run a full DNS server just to override 1 or 2 names (let alone working through whatever complications that would bring). Luckily, some more search led to possible solution RPZ, or response policy zones! I didn’t have to setup a duplicate copy of azurenight.com! I could just run a copy of BIND and overwrite any names I want to return the internal IP address of my server. Point everyone to that BIND server for DNS resolution when on my LAN and voila! Simple solution.
