Universal locking rules (ULR) UI is designed to manage filtering rules on multiple DPIs simultaneously using a graphical interface.

Equipment or virtual machines with the following characteristics are suitable for the subsystem:

1. CPU 2.5 GHz, 2-4 cores
2. RAM from 8 GB (mainly for sphinx)
3. Hard drive (HDD) 50 GB - 250 GB
4. Cent OS 7+ operating system (we do not recommend to not install minimal, because most of the dependencies will have to be installed manually)
5. Network Card (NIC) from 10 Mbps

The subnet configuration is handled with .env file.

/var/www/html/dpiui2/backend/.env

The file contents:

#Redirect URL for "White list" service
ULR_WHITE_LIST_REDIRECT_URL=https://google.com

#The period after Ulr tasks data is deleted (days)
ULR_QUEUE_DELETE_TASKS_DAYS_INTERVAL=1

To use the Universal Locking Rules UI, you need to activate the ULR-license in DPIUI2 with a command:

dpiui2 ulr_lic --make=1

Next:

1. Enter license level: standard
2. Enter the license completion date in the Y-m-d format (e.g. 2099-12-31)
3. Enter the license password.

If the data is correct, a success message will be displayed:

dpiui2 ulr_lic --make=1
 Enter level:
 > standard

 Enter expire date in Y-m-d format:
 > 2099-12-31

 Enter password:
 >
