I've already done this for my other devices but the Chromecast has Google's hard-coded DNS servers...so you have to change it manually for the CC with iptable. (From what I've read)
I want to change my Chromecast's DNS server. I've been searching for how to do this on my RT-AC66U and it seems like this is the place to ask.
It sounds like I am unable to do this with normal Asus firmware and I will need to change to Asuswrt-merlin firmware...is this correct?
Thank you
