Hello everyone,
Can't find any info online about this. 
I'm using the drayDDNS.com for remote access. Should the 'Domain Name Allowed' field be populated with this: subdomain.drayDDNS.com?

No, IIRC that is a basic form of filtering, I can't ever remember using it though.  If you are exposing the management interface to the internet I would strongly recommend setting up IP objects for your trusted devices/LANs then add these objects to the "Access list from the internet" which is found on the same Management screen as your screenshot.  That will ensure that you have control of what devices can connect remotely and you're not exposing the admin console to the internet which would make it an easy target for brute force attacks etc.

Thank you ctluk.
Yes point taken about allowing remote management.
I'm just in setup mode at the moment.
I was just curious about the domain field as I couldn't find any documentation on it.
Thanks again
Zac
