DNS does not resolve corectly our public web site if internal and public domain name are the same

[Guest]

I recently implemented firewall for our organization and since I get ride of old proxy box we encountering following problem... internal users cannot view our public web site, besicaly because our internaly DNS does not resolve it... which makes seans since our internal and external domain are the same.. everything else works just fine. Here are some additional info.. DHCP assigne IPs and forwards info about default gateway and internal DNS to clients... internal DNS then has info about forwardes (ISP's DNSs) ...
Question what I can do so internal users can view our public web again? I know one way of doing it where I can add Alias in our internal DNS named www and browse to dns1.domain.com, but this I believe works only when web sites is on IIS in house, but won't work if public web is hosted by someone else.

Thank

Usually, all you need to do is add a host named www, pointing to the IP
address of the website.
There are rare cases when this won't work, because the ISP has the website
on a box with a dynamic IP.
If you will post the website name I will give you step by step instructions
on creating the record you need.
