This article describes in detail how to set advanced options for wireless routing and how to solve IP address conflicts, I believe that reading this article will help you.
Nowadays, many ordinary consumers only use a relatively small part of the functions to buy wireless routers, but simply use the wireless connection function of wireless routers to access the Internet or transmit data, I do not know much a
The so-called multi-IP setting means that multiple virtual interfaces and different network segments are bound to a single network interface. That is to say, the isolated user can be connected to a single network interface at the same time, when you access the Internet through the gateway, you can also set up different interfaces and CIDR blocks to communicate with each other, because the user accesses the Internet while establishing a bridge for mutu
IP address routing and dynamic routing protocol (6)
Routing is one of the most important functions of IP addresses. The selected data packets can be generated by a local host or another host. In one case, the host must be configured as a router. Otherwise, the datagram obtained through the network interface will be dis
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

To achieve this, I log on to the backend management interface of the Broadband Router, temporarily disable the DHCP server, save the backend pa

2, then we on the left side of the router, click on "Security Settings" and then in the "Firewall Configuration Interface" To open the firewall (the main firewall switch). As shown in the following illustration:
3, select the default filter
set the default gateway to the lan ip address of the router in the TCP/IP attribute of the LAN Nic, and set the DNS to the lan ip address of the DNS server in the network, see figure 1.

Step three : Click "LAN port Settings " to enter a new LAN port
The following command creates an I P standard Access table: access-list Access list number {permit | deny} source [source-mask]
In this command:
◆ Access list number: determines which access table the entry belongs. It is a number ranging from 1 to 9.
◆ Permit | deny: indicates whether the entry permits or blocks information traffic from a specific address.
◆ Source: determine the source I P address.
◆
Address AllocationSystematic addressing enables us to use all possible addresses because our address groups are continuous;
Variable Length Subnet Mask (VLSM)VLSM provides the ability to include multiple subnet masks in A primary class (class A, Class B, and class C) network, as well as the ability to subscribe to one subnet. It has the following advantages:* More effective use of
today, friends send a glorious route, set up a bit, the main is to prevent others rub the net, with one hours, finally set up to complete, to give you a demonstration.
1, take a look at this small white bar, pay attention to the line, and then look at the bottom, generally speaking, the route set URLs are at the bottom, and this is someone else used, the beginning did not log in . Hold down the front light for 10 seconds, the other routes are three seconds, and restore the factory settings .

WhenVroWhen a packet that does not know the IP address of the router, that is, the router does not know the target route, it will try to send an ARP broadcast for resolution. If a target host re
In some wireless networks, because of the large number of clients, to facilitate the management of these machines, many administrators use the DHCP service provided by the wireless router to provide clients with TCP/IP parameter configuration, such as IP address, gateway address
Multilayer Switching (MLS) is an Ethernet-based route exchange technology that provides a layer-3 Switch with an existing router. This article includes IP-only MLS; ipx mls and multicast MLS are out of the scope of this article.

use is divided into four categories: 1. Reserved multicast address (224.0.0.0~224.0.0.255): These IP addresses are not assigned to specific users, and are primarily allocated to multicast routing protocols. IP packets that use this multicast address are not forwarded by the rou
