There is no problem in testing VPN via intranet in the lab, but it won't work when it comes back in the house VPN ServerWhere is the fault possible?When a client establishes a connection with an ISP (this connection uses the Point-to-Point Protocol in the VPN connection-PPP-part), the ISP assigns the client an IP address, a DNS server address, and a default gateway. When the client initiates a PPTP connecti

Objective: IPSec (internetprotocolsecurity) is an open standard framework structure and a long-term direction for secure networking. It provides proactive protection through end-to-end security to prevent private network and internet attacks. In communications, only the sender and receiver are the only computers that must understand IPSEC protection. Secure and secure communication between workgroups, local area network computers, domain clients and servers, branch offices (physically remote in

to connect to the mobile phone. Now you can use/dev/input/ttyacm0 as a common Modem for communication and prepare for a dial-up connection. For example, "Call home" shows how to use the popular dialing program wvdial for dialing. ----Call home To use the wvdial dialing program to dial data through a mobile phone, perform the following steps. Step 1: add the modem to/etc/wvdial. confFirst, add your modem to wvdial. conf. After addition, other tools such as Red Hat Network Manager can be used to

capacity, using BAP/BACP/MLPPP and other protocols to automatically allocate B channel to adapt to large data volume business, such as downloading files, pictures and even real-time voice and video, The B channel is automatically freed when the peak of data volume is past. The process of allocating and releasing B channels is transparent to the user. Because the SVC connection always exists, the user does not have to redial every time it is received, and the

Some people may say that a network administrator will configure a route to achieve multi-PC Internet sharing. Although this is an absolute point, it is not biased. Theoretically, a network administrator must first learn these things. Of course, it is common to learn to write and forget words, and the details of Route configuration will inevitably be forgotten. This article will detail every step you need to take to configure a route for multi-PC Internet sharing. I hope you will be able to wake

router Configuration Guide It is relatively easy to implement the basic configuration of the router so that the computer can share the Internet through the router. The following content of this document mainly describes the following parts: 1. Collect and judge the information to prepare for configuring the router; 2. Enter the vro management interface and configure the vro; 3. Simple troubleshooting during configuration! 1. Preparations before vro configuration (if you know your connection met

How can I use the ping command to obtain the best MTU?What is MTU? MTU is called Maximum Transmission Unit in English. MTU refers to the maximum data packet size (in bytes) that can be passed over a layer of communication protocols ). The maximum transmission unit parameter is usually related to the communication interface (network interface card, serial port, etc ). When can I change the MTU value? For general router devices, the best MTU value is usually the default value. Sometimes, changing

The vro is also connected to a port of the vswitch. Its function is only for nat, re-encapsulate the original address of the package and the destination address of the returned package (see the original post). If the Intranet host wants to send pa
