DNS question

Hi everyone,

   I am venturing tentatively and carefully into DNS (Bind 9.2.2) with 
the help of my trusty O'Reilly book but I have hit a snag that I am 
hoping someone here might be able to help me over. Here's the setup:

   I have two machines on two public IP addresses (209.167.86.46 = 
ns1.alteeve.com, 209.167.86.38 = ns2.alteeve.com) which currently are 
behind a firewall blocking port 53 (I am waiting for our ISP admins to 
respond to fix that). In the mean time though I have made pretty sure 
that the config file and zone files are okay (using 'named-checkconf' 
and 'named-checkzone') and everything looks okay.

   Now, knowing that the DNS servers are not yet available on the web I 
decided to try testting the servers on the LAN behind the firewall. To 
verify that the ports are up and listening I used 'nmap' to check the 
ns1.alteeve.com server; ports 22, 53, 111 and 1026 are accessible (from 
behind the FW only). I have 'named' running, too.

   Now despite all this when I try to use 'dig' or 'nslookup' 
(specifying the local IP as the server as the name 'ns[1|2].alteeve.com' 
will not resolve until the DNS servers are live) I get server timeout 
(can't connect). Now, the DNS is configured for the zone 'madisonave.ca' 
so that is what I try to resolve in the following examples of what goes 
wrong:

[root-uRZ2/RANkOA at public.gmane.org boot]# dig @209.167.68.46 madisonave.ca

; <<>> DiG 9.2.2-P3 <<>> @209.167.68.46 madisonave.ca
;; global options:  printcmd
;; connection timed out; no servers could be reached
[root-uRZ2/RANkOA at public.gmane.org boot]#

[root-uRZ2/RANkOA at public.gmane.org boot]# nslookup
Note:  nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
 > server 209.167.86.46
Default server: 209.167.86.46
Address: 209.167.86.46#53
 > madisonave.ca
;; connection timed out; no servers could be reached
 >

   Would it help if I posted 'named.conf' and zone files?

   Thanks everyone!

Madison
