ADSL/VDSL PPPoE: A computer runs a third-party dialing software such as Enternet300 or a dialing program provided by WinXP. Fill in the ac

Cisco configuration instance _ Cisco dual-Egress NAT configuration objective: to simulate the routing function based on the original address policy when a dual-Egress link is available, and access to the external network from different original addresses is realized, in most cases, the vro uses NAT to translate the Intranet address on the external port, so this experiment also uses dual NAT to translate the internal address to enable Internet access through multiple ISPs. Environment Description

What is Internet Traditional and non-traditional Internet terminals, all of which are called host or end systems. The end system is connected by a communication link and a packet switch. When data is transmitted from one end system to another, the sender system segments the data and adds the first byte to each segment. The resulting information package is called packet ). A group switch receives a packet from an inbound communication link and forwards the packet from an outbound communication li

! How to crack it !!! I suspect that I have set it on my account. I can only dial at 2.5! I tried to use two PCs to access the Internet as long as I use Star dial-up speed, so I suspect that China Telecom has not bound my NIC address. By the way, I used the cat and switch shared by Alcatel! Another idea I had was to manually use the star speed dialing + the cat routing function of Alcatel in a PC = shared Internet access. I tried it, that is, the cat dialing is required for simple debug

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

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
