![]() Let's say you configure HTTP Policy for this rule to block connections to the domain. The HTTP Access Access Rule allows all users on the Internal network access to all sites on the External Network using the HTTP protocol. However, HTTP Policy is applied to machines that are explicitly configured as Web Proxy clients, even when the Firewall, SecureNAT and Web Proxy clients access the site using the same Access Rule.įor example, suppose you create a rule named HTTP Access. One side effect of bypassing the Web Proxy filter is that HTTP Policy is not applied to the SecureNAT and Firewall clients. ![]() 6.Ĭlick OK in the Apply New Configuration dialog box. 5.Ĭlick Apply to save the changes and update the firewall policy. On the Parameters tab, remove the checkmark from the Web Proxy Filter checkbox. In the HTTP Properties dialog box, click the Parameters tab. On the Toolbox tab, click the Command Protocols folder and double click the HTTP protocol. ![]() In the Microsoft Internet Security and Acceleration Server 2004 management console, expand the server name and click the Firewall Policy node in the left pane of the console. Perform the following steps to disable automatic Web Proxy connections for Firewall and SecureNAT clients: 1. However, a single machine cannot act as both a SecureNAT and Firewall client for Winsock applications that communicate using UDP or TCP. The Firewall client is compatible with all ISA 2004 client types. The Firewall client requires software installation the software is supported by all 32-bit Windows operating systems with the exception of Windows 95. You can automatically configure the Web browser as a Web Proxy client at the same time the Firewall client software is installed. If you are not using SMS, the logged on user must be a member of the local administrators group to install the Firewall client software. The Firewall client can be deployed via Active Directory Group Policy, via SMS, or via a silent installation script. The Firewall client can automatically find the ISA 2004 firewall through the use of WPAD entries in DHCP or DNS. The only requirement is that the Firewall client machine know the route to the Internal interface of the ISA 2004 firewall. This makes the Firewall client relatively independent of the current routing infrastructure. The Firewall client intercepts all TCP and UDP communications from Winsock applications and “remotes” them (sends them directly) to the ISA 2004 firewall. If you configure an Access Rule that allows access to all protocols, the Firewall client will be able to access all TCP and UDP protocols, even if there is no Protocol Definition for a particular protocol. The Firewall client does not require a protocol definition to access a protocol. The Firewall client supports secondary connections without the aid of an application filter. The Firewall client can send user and application information to the ISA 2004 firewall and have this information stored in the log files.
