Experimental environment: Here we use a Huawei s3526 switch to simulate Internet two H3C firewalls, two quidway s2403h-hi switches Two 192.168.1.0 and 192.168.2.0 network segments are connected by the two sides of Huawei's firewall respectively Achieving cheap connectivity using VPN technology To allow two LANs to communicate with each other, the GRE tunneling technique is used between two firewalls (the so-called tunnels are logical virtual) Experimental purposes: The GRE tunneling techno

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

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

connection method, you can directly jump ); the first thing to confirm is what your "Broadband Access Method" is like? Of course, the simplest way is to give a call to your ISP Internet Service Provider. You can also make a quick judgment by using the previous network connection method of the router you purchased. 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

The following describes the classification of VPN from different angles. 1. divided by access method This is the most important VPN division method for users and carriers. Under normal circumstances, the user may be on the leased line (Nat) network, or dial-up Internet access, depending on the specific circumstances of the su
