Dynamic ip dns settings

Previously, monitoring devices were configured for the company. 3322 free dynamic domain name resolution is used. today, because one of my friends has restored the router to the factory. you need to reset it. I forgot how to configure it. it took dozens of minutes. it took 10 minutes to complete the configuration. record it here. so that you do not forget it next time.

1. register an account
There are a lot of companies that provide dynamic IP resolution. Here I provide a few keywords. [3322] [peanut shell] and so on. There are prompts in the routing settings that you can choose your own.
Here I chose a peanut shell: http://www.oray.com/
After registration, select my console> product management> domain name management> free Domain Name
Check whether the domain name they sent you is activated. If it is not activated, the small color icon in front is gray-white.
If it is activated, you don't need to worry about it. If it is not activated, select the domain name and click. Activate the peanut shell.

2. Set vro
There are also many kinds of routers, but they are similar. Here I am using tp-link.
Enter vro → Dynamic DNS → select a service provider and enter the account and password → OK!

3. Set the dmz host of the vro
Set the IP address in the host network of your server to a DMZ host.

4. Success
Now, if your intranet host can be accessed by setting up an Intranet environment, you can also access the internet. You are not afraid to switch the IP address because it will automatically update the dynamic IP address to the peanut shell.
