So just check the open port for IP
For users who hire frequently Firewall On a VPS, you may not be confused about the meaning of open port or what that open port means. Because only by checking the port can one conclude that the port is really open.
Usually there is a VPS service that blocks a port for some reason, for example some free time or attempt for a couple of days so users don’t use it for weird things.
Although it can be tricked in a number of ways, one of them is editing iptables manually and the blocking can be unblocked. However, users should not do this as it is intended to harm others.

And what is discussed this time is only in the form of check open portswhether the port can be opened properly by the user network or not. So let’s say this is some kind of debugging thing.
Can also be used for routers if possible, but most people use it more often to test if a port is open on the current network. I test it myself more often when I’ve finished editing iptables do Port forwardingso that it can be determined later whether it was successful or not. Okay, that’s how it works.
Prepare the IP to be tested in advance. This can be the local IP or the VPS IP of the user. Go to the website You get signal.
Notice the crevice Remote address Fill it with the IP you created earlier. Then the port to be tested is entered in the column next to it, whether it is open or not. Continue by pressing the button Submit.
Then a notification appears under the column that the IP with the port is open or not. When it’s open it looks like this.
If the port is not open in the meantime, such a notification will be displayed.
This is a very convenient option, in my opinion, compared to using a program because what users need is just a browser. In the meantime, if you use another program, it’s just a burden if you just want to test the port.
In addition to the websites mentioned above, there are several other similar websites, but only You get signal the best for me because the site is easy to use and not difficult. In this way you can still check whether the port is open or not, even with slow connection states.

Whatever it is, use the above method wisely without harming others.
