Hello,

there are two PCs, one router and one switch in your project. All can ping each other. Where is the server ?

[TranHoangMinhNguyen5339]

At the right-bottom. What you have seen is not my problem. I'm sorry about
forgetting to mention it.

Hello,

attached the revised version, it looks like you were using the wrong cable. Also, the server had the same IP address as the default gateway...
