The internal interface must be placed in the same network as these computers. In this example, this configuration is accomplished by assigning the internal interface the IP address of 192.168.2.1. The external interface of the ProLiant DL320 Security Server is assigned an Internet IP address that is determined by your ISP.

NOTE: IP addressing can be a complex issue. If you do not understand how the IP addresses were assigned to computers on your LAN, consult with a networking professional who can assist you with network IP addressing issues.

1.Before installing the ProLiant DL320 Security Server, determine the network ID used on the network directly connected to the internal interface.

2.Assign the server an internal IP address on the same network ID as the other computers on the directly connected network of the internal interface. If you are not sure what internal IP address to assign to the server, consult with a network professional.

DNS server address on the internal interface

The ProLiant DL320 Security Server must resolve names to IP addresses. For example, each time the web browser is used to connect to a website on the Internet, that name is sent to a DNS server to match (or resolve) that name to the IP address of the website. After the web browser has the IP address of the website, it connects to the website using the IP address.

The ProLiant DL320 Security Server must be configured to use a DNS server that resolves Internet computer names to IP addresses. There are several ways to do this:

Install a DNS server on the LAN, configure that DNS server to resolve Internet host names, and configure the server to use that DNS server.

Use the IP address of your ISP DNS server. The DNS server at your ISP will be able to resolve Internet computer names, but it will not be able to resolve computer names on your LAN.

Install and configure a DNS server on the server. This DNS server would be able to resolve both Internet computer names and computer names on your LAN.

Microsoft Internet Security and Acceleration (ISA) Software specifications

HP Microsoft Internet Security and Acceleration (ISA) Software is a robust network security solution designed to safeguard business environments by offering a versatile platform for secure internet access. ISA Server integrates multiple functionalities that are essential for modern enterprise needs, helping organizations manage and protect their network infrastructure.

One of the main features of ISA Server is its firewall capabilities, which provide an essential barrier between internal networks and external threats. The software utilizes intelligent packet filtering to analyze incoming and outgoing traffic, ensuring that only legitimate communications are allowed while blocking potentially harmful activity. This helps to mitigate risks associated with external cyber threats and unauthorized access.

Another key feature is the built-in web caching technology. ISA Server improves network performance by caching frequently accessed websites and content. This reduces bandwidth usage and enhances response times for end-users, leading to increased productivity. By storing copies of web pages, ISA Server can serve them quickly to users, allowing enterprises to optimize their use of internet resources.

ISA Server also includes a powerful Virtual Private Network (VPN) feature, enabling secure remote access for employees. This technology supports secure connections over the internet, allowing users to access the corporate network and resources from anywhere in the world. The VPN capabilities ensure data encryption during transmission, protecting sensitive information from interception.

Moreover, ISA Server incorporates integrated threat management tools, which offer insights into potential security issues. These tools provide logging and reporting features that allow administrators to monitor traffic patterns and detect anomalies. This functionality is critical for identifying and responding to potential security breaches in real-time.

In addition to these features, ISA Server supports application-layer filtering, which enhances security further. This allows organizations to control access to specific applications and services while ensuring that malicious content cannot infiltrate the network.

Overall, HP Microsoft Internet Security and Acceleration Software is a comprehensive solution designed to address the complexities of network security in today’s digital landscape. Its combination of firewall protection, web caching, VPN capabilities, and application-layer filtering makes it an invaluable tool for organizations looking to secure their internet connectivity while optimizing performance and user experience. By leveraging advanced technologies and characteristics, ISA Server empowers businesses to operate safely and efficiently in an interconnected world.
