Dear KP and all other LEAF addicts,
no wonder you were not aware of this fact, since it is
only due to my badly phrased question and the fact that
Shorewall had a say in this matter: I had forgotten to
allow inward dns queries on my 3.0-router. Sorry for
any alarm this may have caused!
There is however a true related issue going side by side
with my original posting. It concerns reverse lookups.
Consider these two statements for Dnsmasq on a Bering router:
bogus-priv
server=/3.168.192.in-addr.arpa/192.168.3.252
The naive understanding would be that reverse lookups for
192.168.3.0/24 would be sent to a server at 192.168.3.252
for answering. This is not true since Dnsmasq is intentionally
coded to let the "bogus-priv" get the counter-intuitive
precedence. I mailed the maintainer Simon Kelley the other day
and he responded that the issue is raised from time to time,
but he is firm in not changing the present ordering. Thus
the only reverse lookups within 192.168.0.0/16 that Bering
will do, when using "bogus-priv", must be located in a local
hosts-file or arise as dhcp-leases on the router itself.
Simon Kelley gave me this link for the Debian-way to
partially work around this issue
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=461054
There was another issue with NXDOMAIN-responses that was
resolved in the 2.41 issue of Dnsmasq, so the next beta
of Bering-uClibs might take that into consideration.
Best regards
Mats E A
