About the DDNS of DrayTek 2920n

[LosAngeles]

Hi,

I am using the DrayTek 2920n and found a problem in the Dynamic DNS configuration. Recently, I have changed the ISP and found that they put a transparent proxy at the back. Therefore, I found that the DrayTek router will update the wrong WAN IP address (Update the transparent proxy IP address) to DynDNS server instead of my real WAN IP address. However, I can access my established server using the real WAN IP address from the outside network. Is there any method to solve such DDNS problem?

Thanks and Regards,

Jacky

*** p.s. I am using dyndns.org service

Hi 門神,

I am in Hong Kong. I have already viewed the DDNS log of DrayTek router. It said that the updated WAN IP address is the transparent proxy IP address. In other words, that IP address is not matched to the WAN IP address shown in the "Physical Connection" section of the DrayTek router.

Thanks and Regards,

Jacky

DDNS Update View log 是 OK 的

兩種測試方法出現同一個結果

工具-查自己的電腦虛擬IP和分享器真實IP

這是Web直接偵測上網IP

台灣Tracert 對方提供的IP在某一個節點之後斷掉
