According to the usage specifications and strict requirements of the server, we actually need to configure a security group firewall for each server host. For example, we have used Alibaba Cloud and Tencent ECS to determine whether merchants have mandatory authorization ports to use them. However, there is no restriction for Vultr service providers to use firewall by default. However, if necessary, we can authorize security group firewall rules for each server separately.
In this article, let's look at how to create firewall firewall rules in the background panel of Vultr server, and then authorize them to different ECS hosts.
We logged in to the background of the VULTR account and saw the FireWall menu. At first, we did not create firewall rules. We were going to create one.
At first, we need to create a firewall rule name.
Then we are familiar with this. Add port clearance as required. Some of them have their own quick addition, and some need us to add TCP ports ourselves. For example, 8888 and 888 ports are the ports we need to set if we install the pagoda panel.
After setting, we need to find Firewall in the current server Settings and select our firewall. Find the firewall rules that we need to take effect on the current ECS host, and confirm that they will take effect after being updated.
In conclusion, if we need to use different firewalls for each server, we need to set different firewall rules. Generally speaking, we can set a unified firewall. Have you learned how to set firewall rules for VULTR servers? The default setting is not mandatory, but we can also set it as needed.
