Model: Deco M5  
Hardware Version: V3
Firmware Version: 1.6.0

I have a Deco M5 but i appear to have two external ip addresses?

 

One as reported by Deco is correct, but the ip address being reported to tplinkdns.com is wrong as my bookmarked links to my internal devices does not work. All the ports are open and forwarded to the correct places.

 

Any ideas as ot what might be wrong?

  @Richyboy1980 

Hi, It is suggested to update Deco M5 to the latest 1.6.1 firmware first:

https://static.tp-link.com/upload/firmware/2022/202209/20220920/Deco_M5_1.6.1_220818.zip

 

And is there another ISP router in front of Deco M5?

Thank you very much.

Best regards.
