and that's concidered a bug?
if no manual or "alternate" dns servers are specified in WAN setup, of course clients are not going to be able to access the internet by url since the router doesn't have an entry for the alternate DNS servers, to assign to the clients.
dns relay on: clients get 192.168.0.1 as DNS server address.
dns relay off: clients get 208.67.222.222 (example) as a preconfigured DNS server address
It would defeat the purpose of DNS relay for it to assign clients the same DNS server IP that is used with DNS relay on.
Is that how it works after the bug fix?
