What is a Gateway, as its name implies, is the "Gateway" connecting a network to another network ". There are also many types of gateways according to different classification standards. The Gateway in TCP/IP protocol is the most commonly used. The "Gateway" mentioned here refer to the gateway under TCP/
The first two sections on how wireless routers set up the PPPoE dial-up, dynamic IP Internet. Since the explanation to, of course, can not miss the IP static mode of Internet settings, the general static Internet mode is mainly used in level two routers or proprietary IP network, such as enterprises in the formation of local area network, many times will apply fo

3. Note A of the IP mask. The IP address without A subnet can be written as A mask with the host number 0. For example, if the IP address is 210.73.140.5 and the mask is 255.255.255.0, you can also use the default mask to write only the

Handle a fault. A host performs one-to-one static NAT on the Cisco router. The host can log on to the device through the NAT address ssh normally, but the host sends syslogs, the obtained
a router, TCP/IP communication between the two networks is not possible, even if the two network connections on the same switch (or hub), the TCP/IP protocol will determine the subnet mask (255.255.255.0) on the two network hosts in a different network. To achieve communication between the two networks, you must pass through the gateway. If the host in Network a

The original residential broadband is a pppoe dial-up connection. When the vro is set to start DHCP, it sets itself to 192.168.1.1. Generally, there is no problem.
Today, broadband is migrated from Binjiang to Yuhang. The residential area is no longer in the pppoe mode, but in the dynamic IP Mode. After the wireless router is connected, the

We can enter the LAN router's background management interface, from which to configure the ARP table settings options, the static ARP routing table personalization, the future LAN router device will automatica
