DNS and DHCP not working on ERL-3 after upgrade to 19.07.2.
I use a ERL-3 as a backup router. I did a clean installation of 19.07.2 and clients receive an IPv6 address but not IPv4
The diagnostics page ping, traceroute and nslookup do not work whether I try IPv6 or v4
However if I ping 1.1.1.1 (2606:4700:4700::1111) or traceroute to 1.1.1.1 (2606:4700:4700::1111) the router receives responses.
I have verified the LAN IP and WAN IP do not match, settings for WAN and WAN6 look correct.
I re-downloaded the firmware thinking the original may have been corrupt but even after verifying the sha256sum on the new download the result is the same.
I have tried using Peer DNS and using Cloudflare's DNS servers for IPv6 and v4 with no luck.
What am I missing here?
