How to communicate between two computers in routers with different number segments

Because NAT is executed on route B, the connection is blocked, and the network structure is disrupted, which is not just a problem of different network segments.

The scheme is as follows. Note that in the following scheme, see the LAN port and WAN port clearly.

1. Change the LAN port IP of router B to be different from router A), change the IP of computer B to 2, and close the DHCP server of router B.

3. Set up a wireless network with the same SSID, the same encryption method, and the same password as Route A.

4. The wireless network of route A and route B uses a fixed frequency band, and the frequency bands of route A and B are different, and it is best to have a difference of more than 5. Recommended

7. Connect the LAN port of Router A to the LAN port of Router B.

This solution not only solves the communication problem, but also enables seamless roaming of the wireless network.

1. Disable the NAT function of router B (NAT cannot be disabled for home routers, so this solution is not recommended).

2. Add a static routing table to router A and point the network segment to the WAN port IP of route B.

Why don't you use a router?

Can hosts on the same network segment communicate with each other? Do hosts on different network segments need routers to communicate?

Hello, dear to your question, Xiao Chen has answered it for you, please take a look at the hosts of a network segment that can communicate directly with each other, because they are in the same subnet, and can directly transmit data. Hosts in different network segments need routers to communicate because they are in different subnets and need data through the router**. In a computer network, the network is divided into many subnets, each of which has a unique network address, usually represented by an IP address.

If two hosts are in the same subnet and the network part of their IP addresses (the good base is the prefix in the IP address) is the same, they can communicate with each other directly without going through the router. If two hosts are in different subnets, the network part of their IP addresses (i.e., the prefix in the IP address) is different, and they cannot communicate directly with each other and need to implement data through a router. The router can connect to multiple subnets at the same time and can determine which subnet the packet should be sent to based on the destination IP address.

Therefore, hosts in the same network segment can communicate directly with each other, and hosts in different network segments need routers to communicate.

Can hosts on the same network segment communicate with each other? Do hosts on different network segments need routers to communicate?

Hello dear, hosts on the same network segment are required to communicate with each other. Yes, hosts on the same network segment can communicate with each other. Network segments are divided based on IP addresses and subnet masks, and hosts must be within the same network segment to communicate directly.

For hosts on different network segments, communication needs to take place through the router**. A router is a device that is able to connect to different networks and transmits packets from one network to another. When two hosts are arguing about to communicate, the packet goes through the sending host's default gateway (i.e., router).

Based on the destination IP address, the router will determine which network the packet should be sent to. As part of this process, the router also handles tasks such as NAT (Network Address Translation) to ensure that packets are accurately sent and received. In short, hosts in the same network segment can communicate directly, while hosts in different network segments need to communicate through the router's **.

Static routing is set to enable the pinging of different network segments of the first-level router and the second-level router, and the L2 router must support the routing mode to achieve this function.

Two routers connected:

1. Wired connection, 1, plug the network cable into the LAN port of the secondary router and connect to the computer to set the LAN port IP address to assign one of the IP addresses to the main router, or wirelessly set the IP address of the LAN port of the secondary router to assign one of the IP addresses to the main router, turn off the DHCP service of the secondary router, and finally connect the network cable to the LAN port of the main router.

2. Plug the network cable into the WAN port of the router, connect the router and set the router to access the Internet as an automatic IP address or a fixed IP address.

Second, wireless connection, the router has a bridging function, and the secondary router can directly bridge the main router. In the secondary router bridging function module, you can search for the main router network and enter the password to connect, and you need to take care of the secondary router DHCP service.

Turn the port on.

Interconnection is fine.
