Hello-

Here is my scenario. From outside of my network, i am
able to reach a web site using the external IP address
that is being hosted within the local network. I have a
firewall that is using NAT that translates the external
IP address to the internal IP address. When i am inside
my LAN, i am unable to reach the web site because the
external IP address is not recognized. How can i
configure DNS to recognize the external IP address and
point it to the internal IP address?

Thanks to all!

Create a forward lookup zone with the site name, ie. www.site.com then
create a new host leave the name field blank and give it the IP of the web
server.
You can create a zone for just "site.com" then a host named www with the IP,
but if you do this if there are any servers located elsewhere, like a mail
server for the domain, you would have to manually create all these records
and keep them up to date. You would be best just using the site name to
alleviate this conflict.

Rather than having a domain name, can i configure DNS
using IP address. For example, i have a website that is
accessed by IP address, http:\\external IP address. When
i am in my network, i am unable to view the site unless i
use http:\\internal IP address. Can i configure DNS with
this scenario.

Thanks!

There is no point in going through DNS if you are just going to name the
zone with an IP address. You don't need DNS to give you the IP address if
you are trying to access the site by its IP address.

The whole point with DNS is to convert domain names to IP addresses, that is
all it does.
