Create an Access Rule Allowing VPN Clients Access 
to the Internal Network 

At this point, VPN clients can connect to the VPN server. However, the VPN clients cannot 
access any resources on the Internal network. You must first create an Access Rule that 
allows members of the VPN clients network access to the Internal network. In this example, 
you will create an Access Rule that allows all traffic to pass from the VPN clients network to 
the Internal network. In a production environment, you would create more restrictive access 
rules so that users on the VPN clients network have access only to resources they require. 

Perform the following steps to create the VPN clients Access Rule: 

1. In 

the 

Microsoft Internet Security and Acceleration Server 2004 management 

console, expand the server name and click the Firewall Policy node. Right click the 
Firewall Policy node, point to New and click Access Rule. 

2. In 

the 

Welcome to the New Access Rule Wizard page, enter a name for the rule in the 

Access Rule name text box. In this example, we will name the rule VPN Client to 
Internal. Click Next. 

3. On 

the 

Rule Action page, select Allow and click Next. 

4. On 

the 

Protocols page, select All outbound protocols from the This rule applies to 

list. Click Next. 

5. On 

the 

Access Rule Sources page, click Add. In the Add Network Entities dialog box, 

click the Networks folder and double click on VPN Clients. Click Close.
