5.6.2.4. ALG
Click ALG in the left pane and the following page will be displayed. The NAT ALG（Application Layer Gateways）function enables the router to support various special application protocols with payloads containing IP addresses and port numbers, and tries to establish connection between these imbedded IP addresses and port numbers. Failure of the transformation of such information may results in problems. The NAT ALG function realizes payload detection and transformation to ensure normal operation of payloads under NAT environment, requiring no special configuration of users.
