Simple description:
The L2tp/ipsec VPN leverages IPsec for data encryption and provides user authentication and computer authentication, that is, verifying the identity of the computer before establishing l2tp/ipsec, and then verifying the identity of the dial-in user. There are two ways in which computer authentication is available: 1. Pre-shared Key 2. Certificate authentication
The following experiment L2tp/ipsec certificate authentication for site to site:

The solution I also put my method to do a bit of experiment, use serv-u do, have a little mistake, but after all do come out, the following summary:
PASV server is placed behind Isa, in fact, is to solve two problems:
1, PASV port. My method above suggests using secondary connection, but it turns out that it's not true that you should create a primary connection for each PASV port, and then create the server publishing rules, how many PASV ports, Ho

1. In RHEL 4, you only need to export http_proxy = http: // localhost: 3128 or http: // localhost: 5865 in the environment variable.
2. In RHEL 5 or centos 5.5, you can access the Internet after export. However, if you perform the yum upgrade, various 403 errors will still be reported. At one time, I thought the ISA was getting too strict, almost ready to directly
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 th
VPN is the abbreviation of Virtual private network, it is simply to use public network link to erect private network, it belongs to remote access technology.
VPN server in the current network application is more and more extensive, today I come to you for a brief introduction of the VPN server configuration and users use VPN to achieve VPN dial-in. There are also more than one authentication method for VPN, which is combined with radius verification, which combines smart card and certificate au
In general, VPN users are connected to the VPN server is to enter the password, if so, in some public places when the password is likely to cause leakage of passwords, resulting in unnecessary losses. Password Authentication protocol Although the hardware requirements are not as high as the Challenge Handshake protocol, however, in terms of security, it is still a distance from the challenge handshake agreement. The specific authentication protocol to be used, the user should be judged according
ISA can not only set the blocking software, but also can block files through the server, such as restricting streaming media.
Step 1: Like the prohibition of communication software, in the main window, right-click the "Access policy from Intranet to extranet" node, execute the "Configure HTTP" command, the Win7 flagship version of the "Configure HTTP Policy for Rules" dialog box.
Select the "Block specified extensions" option in the specified extend
This completes the task by entering the critical steps to create the OWA publishing rule. Right-click on the Firewall Policy node and select New from the pop-up shortcut menu-the Exchange Web Client Access Publishing Rule command to bring up the Create Rule Wizard, as shown in Figure 1.
Figure 1 Creating the OWA publishing rule
After you give the rule a name, click Next, select the Exchange version and check Outlook Web Access, and then click Next, as shown in Figure 2.

Open IE browser on the client, enter Https://mail.loveunicom.com/owa in the Address bar, the first time to open the address will be a little time-consuming. If the previous configuration is not a problem, you will see the OWA login interface shown in Figure 1. Of course, in order to access the URL normally, you need DNS support, the DNS server to which the client points must have a record to associate the URL with the IP address of the ISA extranet ne
There are many people on the issue of FTP a lot, we refer to, discuss. My environment is as follows:

This article mainly discusses the ISA and FTP on the same machine processing methods.
Most TCP services use a single connection, typically a client initiates a connection to a well-known port on the server, and then communicates using this connection. However, the FTP protocol is different, it uses
