The wireless AP generally has only one LAN interface, therefore, when the wireless AP is connected to the network, it will occupy the network interface used by the original host, unless the broadband router has more ports, the wireless AP and the original host can not be connected to the broadband router, thereby sharing the Internet connection.
Fault resolution
If there are no more ports available for broadband routers, you can purchase a wireless router, a WAN port to a broadband
allocate the IP addresses of computers in the network, but in actual use DHCP can cause network instability, such as the lease to get IP again but found that other computers in the network are already using the IP address, Or the DHCP information is frequently negotiated between the computer and the wireless router.
In fact, these DHCP packets can not be completely, for the average home users, the network is not a large number of computers, we can manually set the IP address and other network
here to "Cisco Linksys BEFW11S4-CN Wireless Router" as an example to introduce its specific settings.
As the world's leading network equipment and solutions provider, Cisco Linksys has focused on Soho and home markets, BEFW11S4-CN has a 10/100m RJ-45 port for connecting to broadband modems, four 10/100m RJ-45 Exchange port and a shared uplink port.
After installing the driver, enter the default account a

For example, the SSID of a Linksys device is usually "Linksys". If a network does not specify an SSID for it or only uses the default SSID, then any wireless client can access the network. This has undoubtedly opened the door for hackers to invade the networ

Different architectures depend on the servers behind the firewall
We have several types of architecture that can be used to deploy the VPN platform. The most common architecture for remote access involves creating a VPN Server behind the Perimeter Firewall of the isolation zone (DMZ), allowing specific ports or URLs to access the server through the firewall. DMZ can be set between two diff
A few days ago, I got a shell from the station, windows2000 system. The Elevation of Privilege was successful, 3389 was not enabled, and 3389 was opened. After the server was restarted, lcx forwarded and 3389 logged on.
After entering the server, we found that only one host in the same C segment is 192.168.0.50.
So I felt strange. How can we say that the unit of this station is also small and small? How can we get one .... As a result, the server is in the
You can set the ing between router port ing and port ing, which is a common form of NAT address translation. Its function is to convert public addresses into private addresses, A route-based ADSL Broadband Router has a dynamic or fixed public IP address. ADSL is directly connected to the HUB or vswitch, and all computers share the internet. At this time, there is only one external address for ADSL, such as 61.177.0.7. The internal IP address is a private address. For example, if ADSL is set to 1

Therefore, before you infiltrate, you may wish to create a notebook to save important information. Writing a notebook won't waste much time. Next, we should have a certain understanding of this network. Is it a general Intranet or a domain? Generally, a large company uses a domain. We only need to check it and fi

Firewall Overview
Firewall definition:
An Advanced Access Control device is a combination of components placed between different network security domains. It is the only channel for communication flows between different network security domains, control inbound and outbound network access behaviors (allow, deny, monitor, and record) According to enterprise security policies.
DMZ is the abbreviation of "demilitarized zone". It is called the "isolation
