Hi, I'm looking to use the pfSense integration but want to be able to update individual 'locations' I have setup in the dynu.com web panel. Its not clear in the documentation whether this is possible.

Location1 --> pfsense1
Location2 --> pfsense2

Nevermind. Found my answer on this page: https://www.dynu.com/DynamicDNS/IP-Update-Protocol

Its working now based by location.

You should be able to do so by using the following URL in the 'Update URL' in the PFSense Dynamic DNS Service settings:

https://api.dynu.com/nic/update?username=USERNAME&password=PASSWORD&location=LOCATION

Do keep us updated as to how it works. Cheers!
