What I want to understand is how DNS is working in the basic/default ZS configuration.
i.e. I have a fresh installation of ZS and DNS lookups from my LAN to the Internet “just work”. Obviously this is not a bad thing, but I want to understand where the configuration is for this (I can’t find any relevant configuration in the GUI). I assume that ZS is simply making use of the DNS servers offered by my 2 ADSL connections?
Following on from the above, I assume if I want to change the default DNS servers (i.e. to use Open DNS) then I need to configure a DNS forwarder (as I’ve seen in some of the ZS documentation relating to OpenDNS), but does this automatically disable/overide the default DNS operation?
