Noticed the tread on a caching DNS server, and that brought up a
couple of questions I had.
I have a DNS server set up in my home. I have a FreeBSD 5.2.1 box
acting as my gateway, running ipfw and natd. It routes my one static
IP address from my DSL provider to a set of internal, unroutable IPs.
That part is working fine. Also on that box is a caching DNS server.
The internal IP for the gateway is 192.168.0.1. My problems are two
fold, and may or may not be related.
1) I cannot, from either the gateway or any of the internal machines,
get DNS query responses from 192.168.0.1. I can get query responses
from 127.0.0.1 and the external IP address from the gateway, and I can
get query responses from the external IP from any of the internal
machines (well, partially. See below).
2) When I do set up my FBSD 5.3 box inside the network with the
external IP of the gateway in resolv.conf, I can ping and nslookup DNS
names just fine. However, when I go to use Mozilla (Or any browser for
that matter), they hang on "Resolving host:". nslookup tells me it is
using my gateway as the DNS server, and never tells me it's switching
to another server for queries.
Any ideas?
Are you running some sort of packet filter? If you are, I'd try turning
it off and then see if you still have problems. If you do, then you
know that you need to modify your rules to allow the traffic through the
internal interface.
