Dear All,
I have TP LINK 488T loadbalancer. The device information are as follows,

Firmware Version: 3.7.1 Build 091203 Rel.53376s
Hardware Version: R488T V2/V3 00000000

WAN1 port is set to PPPoE mode. The ADSL modem is set in bridge mode and both works fine. I created a DDNS account at no-ip.com and enable DDNS and set the DDNS information on the WAN1 port on Dynamic DNS page of the router WEB interface. These information are also saved for WAN1 port. I can update my public IP when I click on Connect button on the router interface. At that time it shows Connect status : succeeded! and my WAN IP is correctly reflected at no-ip.com.

when the WAN1 IP address is changed, perhaps the router reboots, the [COLOR="#FF0000"] DDNS record is not updated automatically. At this time the Connect Status shows Not Launching! on Dynamic DNS page. Although when I click on the login button on Dynamic DNS page, it then connect to no-ip.com and update the DDNS record correctly there.

My question where is the problem , in the router configuration or in the firmware?

Your valuable suggestions are welcomed.
Thanking in anticipation.
