Typing this from my phone. I've searched and seen multiple different issues with Double NAT. Didn't find one that applied. Everything has been working fine, internet connectivity, then errors for Double NAT and no DNS Servers. I've made no changes. My cable modem does not provide routing, NAT or DHCP. Ignoring Double NAT (very) briefly causes Internet to go green while it's making that change, then orange. Provider is Comcast.
