RE: DNS Issues after setting up a WAN?



Hello 

The result of "ipconfig /all"  from a Windows PC at the main site is as
follows:

Windows IP Configuration

        Host Name . . . . . . . . . . . . : rs-adm-02
        Primary Dns Suffix  . . . . . . . : 
        Node Type . . . . . . . . . . . . : Unknown

        DNS Servers . . . . . . . . . . . : 192.168.0.1



The result of "ipconfig /all"  from a PC at the remote site is as
follows:


Windows IP Configuration

        Host Name . . . . . . . . . . . . : rs-adm-01
        Primary Dns Suffix  . . . . . . . : 
        Node Type . . . . . . . . . . . . : Unknown
        IP Routing Enabled. . . . . . . . : No
        WINS Proxy Enabled. . . . . . . . : No

Ethernet adapter Local Area Connection:

        Connection-specific DNS Suffix  . : 
        Description . . . . . . . . . . . : Intel(R) PRO/100 VE Network
Connection
        Physical Address. . . . . . . . . : 00-07-E9-82-46-F3
        Dhcp Enabled. . . . . . . . . . . : No
        IP Address. . . . . . . . . . . . : 192.168.1.11
        Subnet Mask . . . . . . . . . . . : 255.255.255.0
        Default Gateway . . . . . . . . . : 192.168.1.226
        DNS Servers . . . . . . . . . . . : 192.168.0.1


If we take the PC from the remote side and simply change the IP address
and gateway, the PC then works fine at the main site.

We have done this arrangement many times before without any problems but
the only difference is that the server was a Windows server.    We had
no problems with DNS then.

I have a strong suspicion that the problem has nothing to do with the IP
configuration of the client PCs but has more to do with the way I have
set up the DNS server on the Linux server.   I believe that my
"named.conf" file and/or my DNS tables may have problems with its
configuration in the way it handles DNS requests over different subnets.

Where are they getting IP addresses from?  Manually configured on the
individual workstations?  Using dhcp-relay on the router to use the same
DHCP server at $main_site?

How about you paste the output from "ipconfig /all" from a) a machine at
$main_site that's working properly, and b) a machine at $remote_site
that's not?
