GajShield Firmware: 4.5 and above

Overview

Live firewall logs on a GajShield firewall provide real-time visibility into network activity, helping administrators understand exactly how traffic is being handled at any given moment.

This feature offers immediate insights into:

  • Allowed and blocked connections
  • Active users and applications
  • Security events and policy enforcement

By monitoring live logs, administrators can ensure that the firewall is operating efficiently and that security policies are functioning as intended.

Why Live Firewall Logs Are Important

Live logs play a critical role in maintaining both network performance and security. They allow administrators to:

  • Quickly identify and resolve connectivity issues
  • Verify that firewall rules are working correctly
  • Monitor real-time security events
  • Gain visibility into user and application behavior

Instead of relying on assumptions, live logs provide clear and actionable information, enabling faster and more accurate decision-making.


The live firewall logs are available at

Diagnosis -> Security Logs -> Firewall Logs

On this page, you will see a button named 'Live Log'.



Click on 'Live Log' button. The new window will provide you with the live firewall logs. You can provide a filter terms or search criteria which will limit the live logs to the criteria provided.

When to Use Live Firewall Logs

Live firewall logs are especially useful in the following scenarios:

  • Troubleshooting Connectivity Issues

When users face difficulty accessing websites or applications, live logs help determine whether the traffic is being allowed or blocked.

  • Validating Firewall Policies

After configuring or updating rules, logs confirm that traffic is matching the intended policies.

  • Monitoring Network Activity

Administrators can observe ongoing traffic patterns and detect unusual or suspicious behavior in real time.

  • Verifying NAT and Routing

Live logs assist in confirming whether traffic is being correctly translated and routed through the network.

 

How to Interpret Live Firewall Logs

Each log entry provides valuable details about network activity. Key elements include:

  • Source IP Address – The origin of the traffic
  • Destination IP / URL – The target of the request
  • Port and Protocol – Type of communication
  • Action Taken – Whether the traffic was allowed or blocked
  • Rule Applied – The specific firewall policy responsible

Understanding these fields helps administrators quickly identify the cause of any issue and take appropriate action.

Best Practices

To get the most value from live firewall logs:

  • Use filters to focus on relevant traffic
  • Monitor logs during configuration changes or troubleshooting
  • Correlate with other logs (such as IPS or web filtering) for deeper insights
  • Regularly review activity to maintain optimal security posture

Conclusion

Live firewall logs are a powerful tool within the GajShield firewall, providing instant visibility, faster troubleshooting, and improved control over network traffic. By leveraging this feature, organizations can enhance both their security and operational efficiency.
