Many programs in the local area network can be applicable, but between the external network and intranet and between intranet and intranet is not feasible. The problem is NAT, this article will introduce the next 5 Nat penetration method, solve the internal and external network exchange. 1. Fully conical (full Cone) NAT Host A and Host B in different

The author of the school through ADSL set up routes to share the Internet. The extranet gateway and DNS are 10.0.0.138, the external network port IP address is 10.0 0.1, and the subnet mask is 255.255.255.0. Self-built sites are placed on the server, on the server has been IIS is installed and set up, and the "Default Web site" IP address points to 10.0.0.1. In the default state, you can access the extranet, but you cannot access the intranet. If yo

1. Overview of Intranet Security After the 21st century, with the rapid increase of information technology in China, the Intranet Information security has received more and more attention. In just a few years, Intranet security products and vendors have emerged. However, it is worrying that although many products and vendors provide services with the concept of

Based on the current situation and problems of Intranet security, the technology alone cannot guarantee the competitiveness, or even the actual protection effect. These core causes of Intranet security problems can be solved only when the security management methods and security product management capabilities reach a certain level. In the face of increasingly complex application environments, administrator

Relatively speaking, there is little information on the Internet, and few people write some detailed information about the Intranet penetration for the reference of their peers. Today, I am only going to give a general introduction to some Intranet knowledge. First, under what circumstances will we meet the Intranet? If your goal is only limited to a small WEB, y

Enterprise Network Security has been paid more and more attention. Not only has the Internet gradually strengthened its defense technology against enterprise networks, but also has been developing Intranet security in China for four years. Users and the market constantly improve and expand their understanding of user security, and the Intranet security technology is also being re-recognized. The

Apt Local source build (can be used for LAN Apt-get source or local source) This document describes the use of Apt-mirror software to build apt local source requirements: Intranet development environment for its specific reasons can not Sisu network, So we need the local intranet source to make it easy for developers to download and install software recommendations: Use a single disk to store source files o

Because the company in the computer room hosting server IP is not enough, but also for security considerations, so that a number of virtual nodes can not directly access the Internet, so I xenserver physical nodes through the use of iptables NAT function made a simple implementation [Root@xenserver-cukxsegi ~]# sysctl net.ipv4.ip_forward=1 #开启转发[Root@xenserver-cukxsegi ~]# Echo ' net.ipv4.ip_forward=1 ' >>/etc/sysctl.conf #让重启不失效[Root@xenserver-cukxsegi ~]# iptables-p FORWARD DROP #将FORWARD链的策略

Intranet address port is the LAN MSSQL address port, the network address port customization.(2) After the mapping succeeds, the external network access connection MSSQL uses the mapped extranet address domain name port.

A simple introduction of squid Through Squid Proxy server to achieve intranet users to share the Internet, configure Squid cache and basic access control to accelerate and restrict access to Web services. For web users, squid is a high-performance proxy caching server that speeds up the intranet browsing the Internet and increases the client's access hit rate. Squid not only supports HTTP protocol, but al

Intranet SecurityThe problem has been hard to solve since the beginning. The most important cause is that LAN technology has been adopting an open and shared resource model since the first day of commercial use. While pursuing high convenience, security will inevitably be affected. According to various published survey data, even in the most optimistic circumstances, the loss caused by Intranet security pro

Intranet SecurityFor enterprises, the problem should start from four levels and take into account the internal network security of the enterprise comprehensively. In terms of it o M, the security of user behavior should be determined. Finally, when users pass layer-by-layer security checks, in addition, enterprises also need to check the security of their infrastructure configurations to ensure boarding security. In response to the above problems, ac

Bkjia.com exclusive Article] Speaking of enterprise network security protection, Internet security technology is mature, such as some firewalls, vulnerability scans, and intrusion detection have been well developed. Many enterprises have emphasized the deployment of Internet security products while ignoring the threat of Intranet security. In many cases, the real threat comes from the internal, and many confidential information leaks are caused by poo

In recent years, network security has become the core content of enterprise network deployment. Intranet is a major component of network applications, and its security has been paid more and more attention. According to incomplete statistics, 15% of the investment in building an intranet outside China is used to enhance the network security of the Intranet. Secur
