Q3: What is SNAT? SNAT (Source Network Address Translation) is a type of Network Address Translation (NAT) that changes the source IP address of outgoing traffic as it leaves a private network to communicate with external networks like the internet. SNAT is commonly used to allow devices on a private internal network (with private IP addresses) to communicate with the outside world, typically through a single or limited set of public IP addresses.
Q4: What are the two steps to verify that SNAT is configured successfully? 1.Check the NAT Translation Table (on the Firewall/Router) 2.Test External Connectivity and Source IP (from the Client Device)
Q5: How to configure the application control log event? Steps to Configure Application Control Log Events on Sangfor NGAF: 1. Log in to the Sangfor NGAF Web Interface Open a web browser and access the Sangfor NGAF management console using the firewall’s IP address. Enter your username and password to log in to the system. 2. Enable Application Control Once logged in, navigate to the Policy Configuration or Security section. Find the Application Control feature under Security Features. Make sure Application Control is enabled. This will allow the firewall to detect and monitor applications on the network. 3. Create or Modify an Application Control Policy Navigate to the Policy section where you can create or modify existing firewall policies. To create a new policy: Click on Add New Policy. Define the source and destination zones, IP addresses, or networks. Under the Service field, select Application Control. Choose the applications or application categories that you want to monitor or control. Sangfor NGAF offers predefined categories like "Social Media," "Streaming," "File Sharing," etc. Define the action (e.g., Allow, Deny, Monitor). Logging Settings: Enable logging for this policy by selecting the Log Allowed Traffic or Log Denied Traffic options. Sangfor allows you to specify if you want to log both allowed and blocked applications or only certain types of traffic. 4. Configure Application Control Logging Settings Navigate to the Log Settings section to enable Application Control logging if it's not enabled by default. Go to Log & Report > Log Settings. Find the section related to Application Control. Make sure logging for Application Control events is enabled. You can also choose to send logs to an external Syslog server or a SIEM (Security Information and Event Management) system for centralized log storage and analysis. 5. Set Up Event Notifications (Optional) If you want to receive notifications about specific Application Control events (e.g., when certain applications are blocked), you can configure alert settings. Go to System Configuration > Notifications. Set up email notifications, SMS alerts, or SNMP traps to be notified when specific application control events occur. 6. Test Application Control Policy To verify that your policy is working, test the Application Control rules by trying to access an application or website that the policy is meant to control (e.g., social media, video streaming). Use a device within the policy’s source network and try to access an application that is blocked, restricted, or monitored by the policy. 7. Check the Logs for Application Control Events After configuring the policy and logging, go to the Log Center to check for Application Control log entries. Go to Log & Report > Log Center. Look for logs related to Application Control. Here, you should see events showing the usage of different applications, including details such as: Source IP of the traffic. Application name. Action taken (e.g., allowed, denied). Timestamp of the event. You can filter the logs by application, IP address, user, or time to quickly locate specific entries. 8. Optimize Logging and Reporting (Optional) Log Retention: Depending on your storage requirements, you can configure how long logs are retained on the device or sent to external storage. Go to Log Settings > Log Retention and configure the retention period based on your compliance or auditing needs. Scheduled Reports: You can also configure scheduled reports that include information from the Application Control logs to get regular insights into application usage trends and security events. Go to Log & Report > Report Center and configure custom reports to include application control data.
Q6: Please find the position to enable the Check Policy Validity in Real Time. To enable "Check Policy Validity in Real Time" in Sangfor NGAF, you can typically find this setting under the policy or security configuration section within the NGAF's management interface. It allows real-time checks to ensure policies are being enforced promptly, improving the firewall's response to changes in the network environment. If you're using the Sangfor NGAF system, look for options related to policy monitoring or real-time validation within the security policies tab of your administrator dashboard. |
