DNS - Internal / External

By Cory.Sharplin ·
We've got two Win2K servers setup outside our main network on a DMZ and our website is hosted externally.

Internal Server IPs
192.168.14.1 and 192.168.14.5

External Server IPs
203.X.X.36 (exchange.X.X.X.au) and
203.X.X.38 (ecouncil.X.X.X.au)

Website IP
203.X.X.197 - www.X.X.X.au

The DNS entry in the real world points to the external IPs.

But our internal on the LAN PC's can't resolve those external address
(due to the setup on our Firewall).

I need to setup an internal dummy DNS record to point (exchange.X.X.X.au and ecouncil.X.X.X.au) at the internal IP's (192.168.14.1 and 192.168.14.5)

When I create a new forward lookup zone (Win2K DNS), PC's on the internal LAN can't resolve the web site address 203.X.X.197 - www.X.X.X.au but they can resolve the (exchange.X.X.X.au and ecouncil.X.X.X.au).

I need everyone to be able to use the same URL internally and externally but the URL must point to the internal IP's if the request was from a PC on the LAN.

OWWW MY HEAD!!

You need to create a host a record and point it to the ip address of your website. your host is www then ip address of your website 202.xxx.xxx.xxx

on your internal dns servers bring up the properties of your zone. use the external dns servers as forwarders for the internal zone. that way any dns queries that cannot be resolved on the internal dns servers will be sent to the external dns servers that do have the correct addresses for the web and exchange services.

I think that should do it for you.

Ok you are going about this the hardway. Go to your internal DNS server and right click on the primary DNS server which you only need one really but two for backup. Then go to properties and then go to the tab forwards and put in there the IP of your external DNS server. Also create a host with the name of www and give it your external ip address of the webserver. Also right click on your forward lookup zone and go to properties and allow for dynamic updates. Also click on the tab zone transfers and allow for zone transfers to any server. If you are using WINS click on the wins tab and select uses WINS forward lookup and put the IP number in there. Naturally on your firewall you have to make sure your DNS you have plugged into the DMZ is an internal address and you have it natted to the outside. After you have all this make sure you external DNS records are updated to the outside world you can check it with two websites one in states which is www.checkdns.net and the europe one is www.codeflux.com/tools you might have to just type the codeflux then click on tools. The reason why you check both is that will allow you to see how far it has replicated. Hope this helps, email me if you have any other questions at wroming@ci.killeen.tx.us
