There must be something missing from my dnsmasq config because I see

Sounds like your gateway is not using dnsmasq for lookups. dnsmasq
tells dhcp clients to use its services, but the gateway you will have
to manually configure in /etc/resolv.conf to send requests to the
local dnsmasq process.
adam@isengard:~$ cat /etc/resolv.conf
domain isengard.localdomain
search isengard.localdomain
nameserver 127.0.0.1
nameserver 194.74.65.68
Perhaps your resolv.conf is causing requests for
client.isengard.localdomain while dnsmasq made an entry for
client.localdomain
Here's a query log:
Jan 26 14:49:13 localhost dnsmasq[31068]: reading /etc/resolv.conf
Jan 26 14:49:13 localhost dnsmasq[31068]: using nameserver 194.74.65.68#53
Jan 26 14:49:13 localhost dnsmasq[31068]: ignoring nameserver 127.0.0.1 - local
interface
Jan 26 14:49:13 localhost dnsmasq[31068]: using local addresses only for domain
localdomain
Jan 26 14:49:13 localhost dnsmasq[31068]: query[A] MFD8FDC7.isengard.localdomain
from 127.0.0.1
Jan 26 14:49:13 localhost dnsmasq[31068]: config MFD8FDC7.isengard.localdomain
is NXDOMAIN-IPv4
So it's exactly what you predicted - but I've read thro the whole config and
can't see what I need to change. Here's my dnsmasq.conf again:
domain-needed
bogus-priv
filterwin2k
server=/localdomain/127.0.0.1
local=/localdomain/
expand-hosts
domain=localdomain
dhcp-range=192.168.0.3,192.168.0.254
dhcp-option=option:router,192.168.0.2
dhcp-option=option:mtu,1500
I think that resolv.conf is wrong - should domain=localdomain and not
isengard.localdomain?
resolv.conf is being constantly rewritten by dhclient3 which is doing obtaining
an ip address via dhcp for the external NIC. I can see now that I had
supersede domain-name "isengard.localdomain"
in the dhclient3.conf - doh! So that was it.
Thanks for your help,
regards
Adam
