Hi, I have a really strange DNS resolution problem.
I have set up and configured a Debian woody box as a gateway and firewall for an internal network connected to the Internet via ADSL. I use the Debian ipmasq package for this. The ISP assigns an IP address to the ethernet interface connected to the ADSL network via DHCP. A private IP address is assigned. The ISP presumably runs a NAT gateway to the public Internet. The ISP also uses DHCP to give you the IP address of the nameserver you're expected to use (they block UDP port 53 to every other address so you can only use their nameserver). This is also a private address (192.168.4.5). Now here's the problem, and it's a really freaky one. All hosts behind the Debian box can access the Net just fine, using nameserver 192.168.4.5 to resolve names. But the Debian box itself can't resolve names. And now's the really freaky part. Using dig to query nameserver 192.168.4.5 from the Debian box as in: dig @194.42.142.4 www.google.com works just fine! But putting 194.42.142.4 in /etc/resolv.conf and doing dig www.google.com doesn't work! How can a nameserver which does accept to do recursive resolution for me when I query it directly refuse to do so when I put it resolv.conf? Any ideas?
