Solve the problem that the server cannot be accessed from the external network and the use of the PHPWAMP port scanning tool

The server cannot be accessed from the public network, the solution cannot be accessed from the external network of the Ali cloud server, and cannot be accessed from the public network of Tencent Cloud.

The PHPWAMP integrated environment supports nginx, iis, apache, asp, php, asp.net, and has many built-in utilities.

The reason that the server cannot be accessed from the external network may be that your external network is not open to port 80. You can use the common tools that come with PHPWAMP_IN2 to solve the problem.

How do you know if you have opened port 80? you can scan it. Phpwamp comes with all kinds of scanning methods. You can scan it as much as you like, and it is also very efficient.

Tencent Cloud, Aliyun, server domain name cannot be accessed, cannot be accessed through public network IP (some IDC service providers' server port 80 is not open by default)

The performance of the error: the internal network accesses normally, but the external network cannot access the website in the site.

Port scan can check whether the external network can access your server through this port, which is usually protected by firewalls and security group rules.

The security rule group can be opened on the server console and the firewall can be turned on on your server.

Ali CVM: enable 80 in the settings of security group rules. When using the server, remember to scan the port to see if the operator closes the port.

Aliyun Security rules document: https://help.aliyun.com/document_detail/25471.html?spm=5176.bbsr289243.0.0.pPBB5o

Tencent CVM: Tencent Cloud backend allows the security group to select the port to be released. Specific setting location: CVM-Security group-Management CVM.
