of the wireless relay function and speed up the network:
In the previous content, we can see that the IP address obtained after the relay wireless router connects to the destination wireless network is 192.168.1.112, So we access the management interface of the destination wireless network TP-LINK device, then, enable its DMZ host and set it to 192.168.1.112, so that our relay wireless router becomes a DMZ
be less than 8 MB. This is suitable for Internet cafes and small and medium-sized enterprises. When selecting a Broadband Router, you must first look at the hardware. Processors, memory, flash memory, Wan interfaces, and LAN interfaces are all important. The processor determines the performance and speed. Memory and flash memory are the basis for function expansion. Therefore, if the hardware model is good, the quality is high, the router functions are stable, and the scalability is good.

Solution: To confirm that the intranet computer can access the server, if the intranet is unable to access the computer successfully, we recommend troubleshooting server reasons.

Possible causes: The server's firewall and antivirus software may be the extranet address as a trusted zone address, resulting in the extranet address can not access intranet servers.
Workaround: Shut down the server's system firewall and antivirus software.

DHCP works based on client/server mode. The use of DHCP server, the network for dynamic allocation of IP address will be unified management, solve the problem of address conflicts, network administrators can avoid manually set and assign IP address trivia. DHCP can automatically assign IP addresses to client workstations that are logged on to a TCP/IP network.

With the rapid development of wireless technology, wireless routing functions are more abundant. Here we mainly analyze the specific characteristics of Cisco WRT160N wireless routing function. The new Cisco LINKSYS WRT160N Ultra RangePlus Wireless-N Wireless Broadband Router is designed in a new fashion and provides a variety of featured Wireless routing features such as Linksys Easylink Advisor (LELA, LELA

Step 1: we must first connect the power of each hardware device. Second, insert the telephone LINE into the LINE port of the modem, and use an Ethernet cable (non-crossover) to connect the Ethernet port of the modem to the WAN port of the router. Then, use an ethernet cable (non-crossover) to connect the LAN port of the router (either of the interfaces provided) to the UpLink port of the hub or switch. Of course, if you have few machines, you can also
applications such as BT and network TV, you can consider using DMZ or UPNP functions generally available for broadband wireless cats.

DMZ is the abbreviation of "demilitarized zone" in English. It is called "isolation zone" in Chinese, also known as "non-military zone ". It can be understood as a special network area different from the Internet or Intranet, used to place some public servers without confidential information, such as Web, Mail, FTP, etc. In this way, visitors from the Internet can access services in

1. What is DD-WRT?
For the sake of respect, it is necessary to give a brief introduction to the predecessor of the DD-WRT, The DD-WRT is a "third-party" firmware, used for Linksys WRT54G/GS/GL or other 802.11g wireless routers based on the Broadcom reference design. Because these routers use the Linux operating system, the manufacturer has released the source code of these firmware based on the GPL terms.
The first version of DD-WRT was developed base

principle:Most wireless routers display the list of connected clients, along with their associated host names, in the DHCP assignment information in the management interface. The list of display host names is derived from the DHCP request packet, which is sent by the client to the router (because the router also acts as a DHCP server). Then, since the request for an IP address does not require authentication, any user who has access to the local network can execute, through its host name, you c
Compared to wired networks, wireless networks have freed us from the shackles of cable, bring us great convenience, at the same time we must also consider that, if not set, within a certain coverage, wireless network is open to anyone, on the one hand, may be easy for strangers to enter their own network, using our bandwidth, On the one hand, it may cause information leakage. Let's take a look at the security configuration in the wireless router today.

At present, companies in the world have adopted three virtualization environments-two inside the network and one in the isolation zone DMZ)-about 150 virtual machines. However, such arrangement means that the hypervisor adds an additional layer for Patch Management. But even so, it still cannot change the key issues of physical machines or virtual
