LAN Multiple route DNS cannot be connected to the network

To help you with the following, you need to set up the router.

Secondary routing is the connection of two routers (A and B below) through network cables, generally when the LAN port of a single product is not enough (now the mainstream is only 4 ports), multiple connections are needed to share the same public network or LAN. Here's a simple way to connect and set it up, in three steps:

First, the first is the wiring, the network cable is from the LAN port of router A, and connected to the WAN port of B.

2. Configuration of Router A:

1) The IP address is (this is the default address of general wireless routers, no need to change).

2) Router A uses DHCP to automatically assign IP addresses, so in [DHCP Server - Static Address Assignment? ] Assign a static address to Router B. The MAC address and IP address are the physical address of Router B and the IP address that will be used for the WAN port setup, respectively.

3. Configuration of Router B:

1) Network parameters -- LAN port setting, IP address from the default to , another network segment.

2) Network parameters - WAN port setting, because router A obtains a static IP address, so the WAN port connection type is set to static IP; The IP address is a static IP address that is assigned.

3) When the DHCP service is enabled, the network segment address can be set by yourself, and after the SSID and password are set, the IP address will be assigned when you connect to the new network with a laptop or iPad.

In this setting, router A is connected to the external network, and router B uses router A to share the Internet through NAT sharing.

The two routers need to turn off the automatic IP address assignment of the wireless router, otherwise computer 2 will be assigned by the two routers when the IP address is not bound. It is recommended that both computers be bound to IP addresses.

Hello, I am glad to serve you and give you the following answers: 1. Cause of the problem: Different LANs cannot communicate directly with each other because they belong to different networks.

2. Solution: In order to realize the communication between different LANs, you can use a router or router gateway to connect them, so that they can communicate with each other. 3. Practice steps:

1) First of all, you need to set up a router or router gateway between different LANs and connect it to the same DNS server; (2) Then, you need to set up the router's routing table so that it can route messages correctly to different LANs; (3) Finally, subnet masks need to be set in different LANs so that they can correctly identify devices in different LANs. 4. Related knowledge: (1) Router:

A router is a network device that automatically identifies data between different networks and routes it to the correct address. (2) Router gateway: A router gateway is a special router, which can route data from one LAN to another.

3) Routing table: The routing table is a configuration tool for routers, which can help routers correctly identify data between different networks and route them to the exact address. (4) Subnet mask:

A subnet mask is a network address that can help you identify devices between different networks correctly and thus achieve cross-network communication.

To connect to different LANs under the same DNS, first make sure that there is a router or switching section stove between the two networks, and that the network topology allows communication, and then configure the router or switch to ensure that the switch has the correct IP address and that the routing between the networks can work properly. After that, you need to configure DNS servers on each network so that they can resolve the domain names of different LANs under the same DNS. Finally, configure the default gateways on each network so that they can connect to different LANs under the same DNS through routers or switches.

I don't know if the landlord has done ip--mac address binding on the company's computer, if not, it is recommended that the landlord do the next binding on the switch.

If you encounter such a problem after the family is binding, one of the 6 computers manually does the ARP mapping (the other 5 are better to disconnect from the network, after all, only these 6 have problems, and it may be a computer conflict between these 6).

I think the method landlord should know.

1.Start --Run ---cmd---arp -d to delete local arp table 2Manually bind the gateway DNS

For example: arp -s 00-aa-00-62-c6-09 and then ping the gateway to try.

Hope mine can be helpful to the landlord!

ps: Do IP--MAC binding on the switch It is also very convenient for Guan Fanchun to manage it in the future, and our company is doing this!

Set the DNS of the system IP setting to a fixed DNSEach city has its own DNS

Your current situation should be able to make the above QQ,It's just that you can't open the Douhu with the web page。。。

Hardware reasons. Check the handover.

Devices with gateways with the same address are not allowed in a LAN.
