DynDNS not refreshing IP on ZTE F660

User_QFVP2

I have a ZTE F660 router and configured dyndns. I have a dyn paid account.

On my F660 I added the following:

• my dyn username and password (also tried with the token)
• service type: dydns
• server: http://www.dyndns.com
• hostname (my dyn hostname)
• WAN connection (my wan connection)

But it does not refresh the IP. My IP changes my ip every 12 hours, but dyndns does not take the new ip when it changes.

Any idea? Thanks
