DDNS not working on Archer C50

Hi,
I configured a DNS record on noip.com and enabled it in the Dynamic DNS sub-menu.
From another network (4G) I tried to reach my new hostname but without success.
I've used tcpdump and it seems that SYN-ACK signal is not sent in reply to the SYN.

Ok. So, then the problem must be that the data packets sent from another Internet connection to your Internet hostname aren't reaching the C50.
Is the IP address you see at noip.com the same IP address you see on the Status page of your C50 in the "WAN" section?
Have you verified the C50's WAN IP address is indeed a public IP address? If it's not a public IP address, then there is another NAT between the C50 and the actual Internet, usually either in the form an ISP-supplied modem router at your home or a Carrier-grade NAT at the site of your ISP.

Hi,
Can you see if the IP address in your noip account is being updated by the C50's DDNS function or if it's not?

Thanks for the support. My ISP is running a double NAT and I contacted them to provide me the DDNS.
