Dear Members, dear Customer Support,

The problem with the no-ip.com DDNS service is that the TL-WR743ND router updates the IP address (after the "Connecting" message), only once, when the the device is turned on or when I click the button manually. After that no more update takes place, not even when the dynamic IP address changes, so the router and the devices on its network will no longer be available over the Internet after a while. What solution do you suggest?
I've tried a lot of settings already, but to no avail. (I cannot use the other two DDNS options, as dyndns.org is not free subscription to comexe.cn requires  a Chinese phone number.)

Your comments and suggestions are highly welcome.

Thank you in advance,
Zoltan
