9. How to enable WAN ping respond?
To facilitate debugging and testing your Internet connections, the Device provides Enable
WAN Ping Respond feature; that is, it allows you to ping each WAN interface¶s IP
address to detect whether each Internet connection is normal. The operation is as follows:
Go to the Security > Attack Defense > External Defense page, select the Enable WAN
Ping Respond check box, and then click the Save button.
After you have enabled WAN ping respond, you can test each Internet connection by
using ping command on an outside host. When you ping the IP address of a WAN
interface, correct responses from the WAN interface means that the corresponding
Internet connection is normal; else, the connection itself is abnormal,
ping response is
disabled on
a device between your PC and Device, or there is a configuration error in the
Device.
