The complete set of ISA Server installation settings

ISA Server Usage Guide

As the use of the Internet continues to expand, security and performance also face challenges. In the past only to provide us with the agency service software gradually in our requirements in front of more and more pale. What do we do? We have chosen to find new software and solutions for enterprises to surf the Internet. In the long run, we need more than just a proxy software, so that employees can access the outside world through this agent, allowing them to perceive the outside world and understand the rapidly changing market as soon as possible. Not only do we need to be active in understanding the world, but we also need the world to understand us. Of course, the security and performance of this time is getting more and more attention of enterprises and users. Of course, a more compelling enterprise network managers to find better agent software is the result of the increase in user and access to the stability of the agent software almost into the geometric number of product of the way to decline. I have tried the proxy server is not very small, each proxy server has been used for more than one months, but are not very satisfied.

Roughly summed up

L Sysgate: The function is too simple, the efficiency is not very high, stability also can;

L WINGATE: The function is moderate, the speed efficiency is also good, the stability is not good;

L WINROUTE: The function is moderate, the speed efficiency basically also can, the stability is also good;

L Ccproxy: The speed is good, but generally there are some more or less problems;

• Internet Connection Sharing: The function is too simple, the efficiency is very general, the stability is also OK;

Let's talk about the general situation of our unit. 8M ADSL access to the Internet, two HP servers, the network Center for 100M to the desktop, the entire enterprise network for the full exchange of network. Enterprise internal so all departments need to connect to the Internet, the Department of machinery about 200 units. There are 4 machine rooms, about 200 units in total. We need to be able to control at all times which sections are available to surf the internet and to control the bandwidth of these sections. can be flexible at any time to control the computer room whether the Internet. The ability to set up several web and FTP sites within the enterprise, and publish them to the Internet through this proxy server, so that friends on the Internet can access those resources ... After using these agents, I gradually began to disappoint, do not really let me satisfied with the proxy server? Finally, we use this Microsoft-issued proxy Server--internet Security and Acceleration Server in our friend's introduction.

First of all, I am definitely not a Microsoft shooter, and Microsoft will never look for a lame shooter like me. Or if you look at the use of my back and the features of ISA, you don't feel like I'm bragging.

Internet Security and Acceleration (ISA) Server can be said to be an upgraded version of MS Proxy that was originally based on Windows NT 4.0. It fixes a number of security and cache flaws based on the previous version, providing faster, more secure, and more intuitive and manageable systems. and the integration of the enterprise-class firewall system and High-performance caching mechanism-that is, the software is not only a proxy software, it also acts as a "firewall" effect.

ISA server is allowed to be installed as one of the three modes of cache mode, Firewall mode (firewall model), integrate mode (integrated model). When the network system needs to connect directly to the Internet through ISA, it is also necessary to protect the internal hosts of the company, then the firewall or integrate mode is exactly what you need. But in many enterprises do not have any relevant Internet host or external already have firewall, but their knowledge wants to be able to speed up the traffic between the network, the cache mode is the most ideal one.
