[Unbound-users] basic local zone use case, nslookup good, ping bad

Hello Unbound Users,


I'm running a server on my home network.  The server runs a wiki and
some other things.  I often work on a laptop which is sometimes
connected to the local network and sometimes external to it.

So I'd like the same URL to resolve no matter which network I happen to
be on at the time.  i.e. If I'm at home the IP is (the
local one) and if I'm not then I need


Enter 'unbound' which I installed to help me with this problem.  

I've told the local network router that the machine running unbound is
the primary DNS:

My servers.conf file:





access-control: allow

do-not-query-localhost: no

local-zone: "" redirect

local-data: " IN A"


local-data-prt: " homedns"


server: div-anchor-file: "C:\[etc]"


And when I try to use this, nslookup is grand but ping is not.  Using
the browser to go to the wiki seems to suffer the same problem ping
does, though if I hit it via the local IP it's all good.



Server:  homedns
