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.
