Department companies use dual-nic connections, but the Intranet segments are the same. For example: Intranet Nic IP Address: IP address of the internal server of 192.168.1.0/24 Intranet Gateway: 192.168.1.254 where the ERP server 192.168.1.253 Internet Nic IP Address: 192.168.1.0/24 Internet access network segment Internet gateway: 192.168.1.1 In this

ScenarioBecause the company's intranet has multiple servers whose http services need to be mapped to the company's Internet static IP address, if you use the routing Port ing, you can only map the port 80 of an intranet server to the Internet port 80, port 80 of other servers can only be mapped to non-Port 80 of the Internet. Non-Port 80 ing requires adding ports to the domain name during access, wh

Because the company intranet has more than one server HTTP service to map to the company's external network static IP, if the port map with the route to do, you can only one intranet server 80-port map to the extranet 80 ports, the other server 80 ports can only map to the outside of the network of 80 ports. Non-80-port mapping in the access time to the domain name plus port, more trouble. And the company p

There are many intranet users without public network IP, which can not access the NAS of intranet from external network. But if the day in the company did not complete, need to go home to complete or temporary transfer of the home of the NAS data, then the peanut stick can be used, the following is a peanut stick for remote penetration of the LAN limit to ask the case, share out to learn with you. First of

In the company, generally have their own intranet, but also have the connection of the outside network (can connect to the Internet), before the development of the company's intranet, and the next thing and then switch to the outside network, very inconvenient, so I would like to have been the method to make the intranet and the external network together. After s

Intranet security management products must be intercepted with ARP Spoofing with caution. With the continuous popularity of Intranet security management products in the market, there are many product patterns with various ideas, but the trend of product homogeneity is obvious, in particular, for terminals to block illegal access to the Intranet, the method is gen

Push through multiple layers to prevent Intranet access failures In order to apply for a permanent examination site for intermediate and middle-level computers, the organization established a standard LAN machine room for students to conduct intermediate and middle-level training and examinations at no cost of RMB 100,000 last year; the local area network mainly includes 36 P4-level founder brand computers, two cascade Cisco-branded 10 M/M Adaptive

Port ing principle To connect a computer on the Intranet to the Internet, port ing is required.Port ing is divided into dynamic and staticDynamic port ing:A computer in the Intranet will send packets to the NAT gateway to access xinlang. the packet header includes the IP address, port, and local IP address and port of the other party (I .e. xinlang network, the NAT gateway will replace the local IP address

, and the financial report system could not handle statistics, all services were interrupted for about five hours, resulting in loss of material and reputation of the company. The final reason is that our company only has a simple access firewall at the internet exit. The company's website and email server are located in the external interface area of the firewall and use public IP addresses. Because the website is attacked and implanted with ARP spoofing Trojans, all office and business PC gate

Rogue DHCP server Intranet attack test Intranet penetration is usually Based on ARP attacks, but ARP attacks are too costly to the Intranet and are easy to detect. Today we are talking about DHCP-based attacks. DHCP-based attacks are easy to understand. First, hackers use their own hosts to forge a DHCP server by forging a Mac address and exhausting the IP addres

Allows AWS virtual machines to access the company's intranet resources (SSH reverse proxy), and aws virtual machinesBackground Today, I want to upgrade AWS Virtual Machine to beta and perform some tests. Since the beta version is only available on the company's Intranet, I need to manually copy the upgraded files to the AWS VM. The original method is easy to understand: However, this is a problem because th

Web intranet penetration implementation based on HTTP/2 HTTP/2 introduces the binary frame separation layer to split requests and responses in HTTP/1.1 into finer-grained frames ), in this way, priority, traffic control, and Server Push are implemented. HTTP/2 can open multiple streams on a single TCP connection to achieve multiplexing; HTTP/2 uses a static dictionary, a dynamic dictionary, and a Heman encoding to compress the request/response header

Today, colleagues have a demand, hope that the Web server in the Nodejs of the corresponding site can support intranet access, and later found to modify the hostname attribute in Express for their own intranet IP can be. But the problem is that our machines are automatically acquired intranet IP, then this time the death of the hostname will not be able to use th

User features of Intranet Security Cases There are a large number of design documents, survey data and other value information that need to be protected with emphasis. In particular, the survey data has been included in the scope of national defense strategic information and needs to be protected with emphasis; The design documents submitted for the customer are relatively large, and the editing software of each professional department of the Design I

An SSRF vulnerability in zhihu main site can detect the Intranet The https://www.zhihu.com/question/38548957/answer/77482000 was found to answer this question.It is really a bit interesting. I answered the question of the subject using actual vulnerabilities. Is intranet security really not heavy? With this vulnerability, I can detect and access the intranet of

In our ongoing build, there is an error alert in the construction of the project. Or the communication between the developers, progress reporting of the transaction, is inseparable from a communication tool. That's The mail. It is certainly not the best option for us to assume the use of third-party mail platforms in our project development. Because the third-party mail needs to support the external network, but the external network is not particularly reliable, if there is a problem with the ne

Whether php can obtain the user's intranet ip address from the internet. if the user connects to the Internet through a router or other devices, php can be used to obtain the intranet ip address of the user, that is, 198. xxx. xxx. ip address like xxx. This refers to access from Internet users, rather than obtaining the intranet where the server host is located!

In our continuous construction, errors or communication and progress reporting between developers are all inseparable from a communication tool, that is, emails. If a third-party email platform is used in our project development, this is definitely not the best choice, because third-party emails require Internet support, but the Internet is not particularly reliable, if there is a problem with the Internet connection, it will not be necessary to delay our construction period. In addition, many p
