DNS Help!

By wleodbd ·
I have an ISP's IP address range from UUNet together with their gateway and their DNS. I try to setup a firewall that I can browse the internet from the inside (the LAN). Can someone show me how to resolve DNS by using winnt. I already register my domain with internic.
Can you show me step by step how to do it?
I would appreaciate a lot.

When the system went in, you should have seen this:

Line from ISP---Router---Your hub and LAN

How you install your firewall depends on the brand. In general, it will look like this:

Line from ISP ---Router---Firewall---Your hub and LAN

You will have to configure your firewall to allow those things you trust to come into your LAN, and block the rest.

When you registered your domain with Internic, you specified two DNS server addresses (also called Nameservers). If these were UUnetservers, then UUnet will maintain your DNS for you. You will send them changes as they occur, and they will update the files. If you have few changes, this may be best.

If you will have your own nameserver(s), and those are the addresses you registered, each of those boxes needs to be an NT server if you are using NT. To turn on DNS, from the network control panel applet, select services, Add, and select 'Microsoft DNS Server' and click OK. The service will be installed, along with a DNS Manager, which will show up in your Administrative Tools (common) menu.

The full documentation is included in the install, but I strongly recommend you buy the O'Riley book on DNS on NT if you plan to do your own DNS service.

Steps:
Create the main zone, yourdomainname.com
Create the reverse zone for your IP addresses.
Add each of your computers to the zone.

There is nothing really difficult, but there are a lot of small steps. I strongly urge you to either let your ISP do the work or read the book very carefully.

Good luck.

You need to configure your firewall in order to permit DNS packets go trought the firewall.

Change wks Ip address to one of the scope assigned by UUnet. Point the default gateway to the IP internet router.
From WinNT go to the TCP/IP properties,and fill the DNS tab.
Host: your machine name or whatever you like.
DNS search order: IP address UUnet's DNS (only one needed). That?s all about DNS
Config your browser to connect trough a LAN
Plug the wks to the internet router with a cross cable and try to browse internet.
Reboot.
Try using and url and using an IP address instead. If url is not working (but IP), then browser is unable to resolve DNS.
Move the wks to the other side of the firewall (lan side). Change Ip address to one of your lan side, and point default gateway, the firewall lan side address.
Again, try browsing using URL or IP address.
If only IP address works, you have a DNS resolving problems.

Good Luck

enhanced answer Nro 3
After rebooting, open a dos box and issue a nslookup.exe You should be attended by UUnet DNS server and should see a response like this:
dns1.UUnet.com
>

let's test the DNS asking for a MX record!
type at the prompt SET QUERYTYPE=MX and press enter
type a domain name like novell.com
The DNS should respond you with the ip address and hostnames that are defined to hold novell's mail.

Good luck
