A UID (or Unique IDentifier) is a unique 16-digit alpha numeric code that identifies your Untangle NG Firewall Server. To determine your NG Firewall UID, go to Config > About.
- If you reinstall your NG Firewall, you will get a new UID, and you may need to transfer any previous subscriptions to be authorized for the new UID.
- If you reset to factory defaults, your NG Firewall maintains its UID.
The UID is also required by Untangle Technical Support and will help identify your server when you call for Technical Support.
