NOIP DDNS update issue

  • Since some months, the update of my noip free ip address is not working. I did check all messages in pfsense log and all seems to be ok. On the noip website, it is the opposite: it is said that the ip as not being renew. This is still the case when I force the update.

  • I suggest you to move to the other services, like
    I have been a client of NO-IP for more then 10 years without any problems, but they have changed the policy of service use and now you have much more problems using their free services.
