Why is a firewall important?

A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between the trusted internal network and untrusted external networks, such as the internet.

Firewalls are essential for protecting networks from a wide range of threats, including:
Unauthorized access
Data breaches
Malware and viruses
DDoS attacks

How does a firewall work?

Firewalls work by examining each packet of data that enters or leaves the network. They compare the packet to a set of predefined security rules to determine whether it should be allowed to pass through.

Security rules can be based on a variety of factors, including:
Source IP address
Destination IP address
Port number
Protocol

If a packet matches a security rule, the firewall will allow it to pass through. If a packet does not match a security rule, the firewall will drop it.

Configuring the Jilin monitoring firewall

The Jilin monitoring firewall is configured using the Jilin Management Console. To access the Jilin Management Console, open a web browser and enter the following URL:

Replace "" with the IP address or hostname of your Jilin server.

Once you have logged in to the Jilin Management Console, click on the "Firewall" tab.

The Firewall tab contains a list of all of the firewall rules that are currently configured on your Jilin server. You can add, edit, or delete firewall rules by clicking on the corresponding button.

To add a new firewall rule, click on the "Add Rule" button. The Add Rule dialog box will appear.

In the Add Rule dialog box, you must specify the following information:
Name: The name of the firewall rule.
Action: The action that the firewall will take when a packet matches the rule. The available actions are "Allow" and "Deny".
Source IP: The source IP address or subnet that the rule will apply to.
Destination IP: The destination IP address or subnet that the rule will apply to.
Port: The port number or range of port numbers that the rule will apply to.
Protocol: The protocol that the rule will apply to. The available protocols are "TCP", "UDP", and "ICMP".

Once you have specified all of the required information, click on the "Save" button to create the new firewall rule.
