 Subject:  MAJOR m0n0wall DNS ISSUE - Please Help

Hi Guys

This one is driving me insane!

I use the DHCP server on my LAN in m0n0wall. I also use the DNS forwarder.

I have setup two DNS server entries in the Genreal Setup section. These 
are the DNS server IP's of my ISP.

Ok here is the scenario. My computer obtains an IP address from 
m0n0wall, after doing a "ipconfig/all" I get the following.

Ethernet adapter Local Area Connection:

        Connection-specific DNS Suffix  . : mydomain.com
        Description . . . . . . . . . . . : VIA PCI 10/100Mb Fast 
Ethernet Adapter
        Physical Address. . . . . . . . . : *(I deleted this)*
        Dhcp Enabled. . . . . . . . . . . : Yes
        Autoconfiguration Enabled . . . . : Yes
        IP Address. . . . . . . . . . . . : 192.168.1.189
        Subnet Mask . . . . . . . . . . . : 255.255.255.0
        Default Gateway . . . . . . . . . : 192.168.1.1
        DHCP Server . . . . . . . . . . . : 192.168.1.1
        DNS Servers . . . . . . . . . . . : 192.168.1.1
        Lease Obtained. . . . . . . . . . : Thursday, 10 November 2005

OK now when I do a nslookup on a domian like google.com I get this

C:\Documents and Settings\Mark Wass>nslookup google.com
Server:  pyro.mydomain.com --------> This is my m0n0wall box
Address:  192.168.1.1

Name:    *google.com.mydomain.com*
Address:  AAA.BBB.CCC.196 -----> Where this is the REAL World IP of 
mydomain.com

I did notice that the first line of the "ipconfig/all" command says 
"Connection-specific DNS Suffix  . : mydomain.com" does this have 
anything to do the problem?

I have checked my DNS settings in Windows and I do NOT have "Append 
parent suffixes of the Primary DNS suffix" option turned on.

This is causing all sorts of problem for me when a LAN client needs to 
do a DNS lookup.

I have noted that when I do NOT use m0n0 for getting a DHCP address and 
I manually assign the IP and DNS servers to my windows client that it is 
not an issue, and all works just fine.

PLEASE will some one help me on this.
