This method dose not work automatically, It seams to only work manually, I have left these notes here for if it is one day fixed. I now have 1 entry per host without using groups.
With NoIP you can optionally group hosts together and update them as one:
For this example we will assume you are:
Note: Check the IPFire WebUI > Logs > System Log > Section: Dynamic DNS. And check it again 15 Min later to see if it still works.
NoIP supports a group password, so you don’t have to use your main password remotely.
User name becomes "myGroup:myAddr@domain.com", if you want to try it.
