Two Linux systems behind Asus router cannot resolve
bellaliant.net using bind9 (host,nslookup or dig)

e.g. host bellaliant.net
where is my Linux box.

Linux systems can resolve bellaliant.net using as resolver

Windows system also behind Asus router can resolve bellaliant.net
using Linux systems as resolver - testing with nslookup on Windows

Asus router can resolve bellaliant.net using nslookup on router
(Merlin firmware)

Linux systems behind router can resolve random domains to lookup, such
as cbc.ca or england.com

dig with +trace on Linux ends like this:

;; Received 489 bytes from in 982 ms

bellaliant.net. 172800 IN NS dns-nb00.aliant.net.
bellaliant.net. 172800 IN NS dns-ns00.aliant.net.
;; Received 117 bytes from in 10142 ms

;; connection timed out; no servers could be reached

Linux can look up dns-nb00.aliant.net and get

but then:

host bellaliant.net
;; connection timed out; no servers could be reached

On my work Linux desktop, I can do the above lookup using
and get an answer.

Since the Asus router can do the lookup, I can add to
resolv.conf as a workaround, but I'm really puzzled as to why this
situation exists.  Does anyone else run their own bind resolver on
Bell FibreOp?  Just dealing with a bind9 resolver, not dealing with
running a domain's DNS.

The failure seems specific to lookup of bellaliant.net while having a
Linux client talk to the Bell Aliant NS for resolving.
