Figure 6.4: The administration console of ISA Server in .NET Compose data matrix barcodes in .NET Figure 6.4: The administration console of ISA Server

Figure 6.4: The administration console of ISA Server use visual studio .net ecc200 generator todraw data matrix for .net UPC Case Code Before you go any f data matrix barcodes for .NET urther, set the View option of this console to Advanced. You must perform some basic administrative tasks after the installation.

These include configuring the routing and setting up a dial-up connection (if available).. The Routing Configuration By default the forw ECC200 for .NET arding of packets from the private network to the Internet is disabled. You can activate this routing function by taking the following steps:.

Internet Security a nd Acceleration Server 2000 (ISA). 1. Open the Propert .NET DataMatrix ies of Access Policy/IP Packet Filter and switch to the General tab.

2. Check the Enable Packet filtering and Enable IP Routing checkboxes. Enabling the routing function is only meaningful if the function is required.

If the ISA Server is deployed as a proxy server, this is not necessary as the clients send their requests to the proxy server, which in turn forwards them to the target server. If you have configured routing under ISA Server, the routing function of SBS 2003 may not be enabled anymore. The routing function of SBS could otherwise disable the security mechanisms of ISA Server.

You should therefore check in the Routing and RAS MMC whether any additional interfaces have been entered.. Configuring a Dial-Up Connection If a dial-up connec visual .net datamatrix 2d barcode tion has been set up on the SBS, the corresponding entry must be made for ISA Server. To do this, take the following steps: 1.

Open Policy Objects/Dial-Up Entry and select New/Dial-up Entry. 2. On the New Dial-Up Entry page (see the following figure) enter a name and a description.

Select the connection from Network Dial-Up Connection. Under Network Dial-Up Account click Set account, enter the username and password for the dial-up account, and click OK..

Figure 6.5: Specifying the dial-up entry in the ISA configuration 6 . Routing and Dial-Up Connections The last step is to Data Matrix barcode for .NET set up routing for the dial-up connection. This is necessary even if the dial-up connection is just a backup for a temporarily unavailable always-on connection.

1. Open Network Configuration/Routing. Select Properties from the context menu of Default Rule.

2. Switch to the Action tab (see the following figure). You can usually retain the Retrieving them directly from the specified destination setting.

It is only necessary to specify settings for an upstream server if the ISP uses a web proxy since it does not allow access to all Internet servers. This is, however, not the case as a rule. If this is indeed the case, you must enter the web proxy of the ISP as an upstream server.

. Figure 6.6: Configuring the routing function Finally, under Auto Data Matrix ECC200 for .NET matic dial-out, specify when the route should be used. If the route is conceived only as a backup, check the second checkbox.

If it is the main route, select the upper checkbox.. The Filter Functions of ISA Server The most important Data Matrix 2d barcode for .NET function of ISA Server is to monitor the data traffic between the local network and the Internet. Different filters and rules are used for the monitoring.

Internet Security a nd Acceleration Server 2000 (ISA). and control functio barcode data matrix for .NET ns. Initially these filters/rules are configured in such a way that all connections over the ISA Server are denied.

This means that the administrator must configure all permitted connections as exceptions. If all connections were allowed to begin with and the administrator"s task was to configure the non-permitted ones, the danger of security holes being overlooked would be too great. The available filter and rule functions are protocol, site, and content rules, and IP packet and application filters.

. Protocol Rules Protocol rules are visual .net Data Matrix used when clients use the proxy client and the ISA Server is configured as proxy server. The proxy server is then entered as the default gateway for the clients.

A protocol rule specifies which protocols the client may use. 1. From the context menu of Access Policy/Protocol Rules select New/Rule and enter a name for the rule.

2. Specify whether response to client requests with the protocol of the rule should be permitted or denied, and then click Next. 3.

In the Protocols dialog specify the protocols for which the rule should be applied. If you have selected the Selected Protocols option there, you can select the protocols from the list (see the following figure). Then click Next.
