Default Web Site 1

Hello, our small office has been battling a problem between our cable modem and firewall router. To make this short, in the midst of fixing the problem, the cable modem company changed its setting so that the cable modem is a pass-through only, and the firewall router acts as a DHCP server. We connect to the firewall router with a server running Windows Server 2003 for Small Business.

Herein lies the problem. We have a web page that customers can access from the outside world, which resides on the server. When we try to access the webpage as a customer would do, we reach the firewall setup menu (after successfull password entry).

What changes do we need to make so that customers can access our homepage again? Please forgive the ignorance, all of us in this office are IT idiots.

Okay... I dont fully understand your question.
It sounds like your customers can access the webpage
but you cannot from within your office? Am I correct?

Customers cannot access our webpage. We are setup with the firewall's internal IP at 192.168.1.1, and the server at 192.168.1.2. All PCs connected to the server get their IPs automatically. On the server we have both an internal webpage and external webpage.

Our external webpage is supposed to be accessed by typing in (e.g.)

http://www.google.com.

Instead, people get the login prompt for the firewall. This may be more an issue with the firewall manufacturer's settings than Server 2003, it's just that I know that this arrangement worked before (cable modem changes and replacement of firewall router with new one).

In addition, we run Exchange on the server. It appears now we can send out emails from our PCs, but inbound emails are not being received.

I'm wondering if these issues are related as our company webpage and our email system use the same domain name (e.g.,

http://www.google.com

and username@google.com for email).

You need to setup "port forwarding" otherwise known by cheaper more user friendly routers as "virual servers".

Point port 80 (www) and 25 (smtp email) to your servers IP address so outside queries get passed to your internal server.

Thank you very much!! We're receiving email and the website is redirected properly. An obvious solution to most here probably, not to the dummies in this office.

One more thing, what is the difference between port forwarding, port triggering, and UPnP forwarding? I see these options on our router. I set up port forwarding, left the others disabled. But UPnP has the port settings you mentioned (along with FTP, telnet, POP3, etc.), just waiting on a specified IP address and enabling.

Behind firewall, you must use a machine name or webserver IP address, which hosts your web content instead of Web name.

E.g., my Webserver is "machine1", IP-> "192.168.1.2" and my URL that people use outside the world to access my Web server is

http://google.com.

If I type in

http://google.com

behind my firewall, I will receive Router's admin page.

I suppost to type in

http://machine1

or

http://192.168.1.2

Hope this helps.
