DNS configuration in site to site VPN

Posted on 2007-03-19

I have a SBS 2003 Server w/ SonicWall firewall at our main office.  We have several remote offices each also have a SonicWall appliance.  We have a site to site VPN established going from remote sites to the main office.  My VPN is established and working but I can't ping NetBIOS name. I can ping IP.  When I add the main offices DNS I can ping NetBIOS but once they take their laptops home they can’t get the internet.  I understand why I just want to know what the best way to setup the DNS portion.

Each user at the remote sites are using DHCP so would it be correct to add my main
office DNS server ( as the primary DNS?

I have also added it as a static entry into WINS but haven’t had time to test it yet.
Thanks for the help.

Yes use DHCP to set primary DNS server as your SBS server.

Also, I tend to set a secondary DNS address as a public dns server. such as those listed at

This means if the VPN fails, at least the site has internet access.
