WHY CAN T TWO COMPUTERS SHARE AND PING EACH OTHER WITH THE SAME NETWORK SEGMENT AND THE SAME GROUP?

If you see it in the same workgroup and the ping doesn't work, then organize a ping probe on another computer to see if you have a firewall installed.

To set up a small home area network, one is set as the primary and one is set as the slave, and it is best for both machines to re-work the system, because sometimes the adjustment is not possible because the system is somewhat too highly protected.

The gateway of segment 1 and segment 3 must be on the Aitai router;

2. All computers need to configure their respective gateways, first test whether the segment can ping the gateway of the segment, and whether the 3rd segment can ping the 0-segment gateway; If the ping is enabled, the computers can communicate with each other if the gateway is configured.

3. Note that network isolation cannot be enabled on the route to ensure that each network segment is ensured.

interoperable; Windows Firewall needs to be turned off for each computer.

In this case, if the routers are all Layer 3 ports, they are connected by default, and if your router is a Layer 2 port, it needs to be a VLAN.

Network segments are different, and the purpose of the network segment is to isolate itself.

Since you want to isolate, you have to not isolate. What is your purpose? Is it isolation or no isolation?

Looking at the question you are asking now, your purpose now is not to isolate. Then you can revoke the isolation and set it to the same network segment.

Thank you for your question.

The router supports multiple VLANs.

1. Open the Network and Sharing Center.

2. Click on the sharing option to open the advanced sharing settings.

3. Just check this one.

The main thing is that your computer is not open to the network and found it.

Summary. When conducting a network test, you need to turn off the firewalls of both parties, as well as anti-virus software, and if the network is different, you need to set their gateway or the port of the ** packet or set up a static route.

After two computers with different network segments are converted through the gateway, one of them can ping the other and the other can't.

Hello, one can pass through the other, and then the other can't pass through this one, smart, you have the other one, and then there is a route-related conversion, so he can pass through the branch of this one, and he doesn't have a hand-related conversion, so he can't find the path gateway for the transfer of training and contracting, so he can't pass through.

When Xunjia conducts network tests on Yinchang Potato, you need to close the firewalls of both sides, as well as the Killer poison software, if you have different networks, you need to set up their gateway or the port of the ** packet or set up a static route.

The firewalls are all off.

The firewalls are all off.

Then you add a static route to this computer.

In the process of communication, it is addressed through the underlying address, which is the MAC address of the network card.

In the beginning, neither end knew the MAC address of the other.

For example, pc1 ping pc2

When the ping starts, PC1 checks whether the IP address of PC2 is in the same network segment as itself.

If so, send an ARP request to obtain the MAC address of PC2.

If you are not in the same network segment, you need to get the MAC of the gateway, hand over the ping packet to the gateway, and let the gateway send it for you.

The purpose of the gateway is to send data to the gateway when I don't know who to send it to.

A gateway is usually the IP address of an interface of a router. In this case, the gateway does not exist, even if you have a gateway, you can't get the MAC of the gateway, so the ping packets can't be sent, so the ping can't be done.

You've explained that it's not in the same network segment, how can you ping? Your home machine can ping out all the machines behind someone else's home route?。。 There is no special need to assign the same subnet mask, and it is mainly convenient for home use

Of course, ping is different, and PCs in different network segments can only be pinged through routing.

Can different network segments still be pinged? That's weird.
