Create the Web Publishing Rule 

You’re now ready to create the Web Publishing Rule. The Web Publishing Rule will configure 
the ISA Server 2004 firewall to listen for incoming requests for your Web site. Because the 
ISA Server 2004 firewall is an intelligent, application layer aware firewall, it will accept 
requests only from external users who enter the correct Web site name to access the site. 
External users, hackers and Internet worms will not be able to connect to the Web site by 
using a simple IP address. 

Perform the following steps to create the Web Publishing Rule: 

1.  At the ISA Server 2004 firewall computer, open the Microsoft Internet Security and 

Acceleration Server 2004 management console and expand your server name. Click on 
the Firewall Policy node. 

2.  Right click on the Firewall Policy node, point to New and click Web Server Publishing 

Rule. 

3. On 

the 

Welcome to the New Web Publishing Rule Wizard page, enter a name for the 

rule in the Web publishing rule name text box. In this example, we will name the rule 
Perimeter Web Server. Click Next. 

4. On 

the 

Select Rule Action page, select Allow and click Next. 

5. On 

the 

Define Website to Publish page, enter a name for the Web server on the 

perimeter network in the Computer name or IP address text box. This is the name or IP 
address of the computer on the perimeter network segment, not the IP address on the 
external interface of the ISA Server 2004 firewall. In this example, we will use the name 
perimeter.msfirewall.org; this name must resolve to the IP address used by the Web 
server on the perimeter network. This can be done by implementing a split DNS 
infrastructure, or by using a HOSTS file entry on the ISA Server 2004 firewall machine. 
Later we will create a HOSTS file entry for the perimeter network machine. In the Folder 
text box, enter /*. Click Next.
