We are hosting our own website, using an IP provided by our DSL provider. If a user types in the web address for our site, it will switch to the IP address of the host machine. Inside our LAN, users must type in the IP to view the website. (I hope that made sense) The system hosting the web site is also connected to the LAN, so it can access an internal database for our sales agents use. The machine in question is a W2k Pro. Our LAN is NT based, and we run our own DNS. Any help would be appreciated.

DNS problem.

Since you host your own internal DNS server(s), you do not have an A record pointing www.yoursite.com to your internal IP address.

I would guess that if you try and go to the external IP address of your web site from your internal LAN, it does not work, right? That is fairly common. You normally can't hit an external IP of our LAN. That is why your internal users can't go to www.yoursite.com.
They are getting DNS resolution from your ISP that points to the external IP address for the site.
So, make an A record in your DNS for www.yoursite.com pointing to the INTERNAL IP address for the web server.
Then it will work for your internal users.

hope this helps

This is how i have setup mine. I've asked my ISP to create a subdomain for my office office.mycompanydomainname.com and asked them to point to my btopenworld static ip address.
Get an old machine with 400mhz processor windows NT put 4 Nics on it tomake a router installed WinRoute pro in it, 2 configured with internal ip and 2 configured with external ips.
WinRoute has ip address mapping, firewall and nat.
My Internal IIS/Mail has a private ip and i have map my btopenworld static ip and port# 80/25/110/443 to my intranet IIS/Mail server ip 192.168.0.7

And it works perfect. I've security and performance under control.

I agree that you can create lots of (a) dns records for your iis server for internal resolution and you can also ask your isp to create lots of sudmain for your office for external resolution since you don't have to pay for it.
