You can limit admin users' login to a set of IP addresses, this feature is turned off by default.

To enable it:

1. Login to your DPOD as root user
2. Execute app-util.sh and stop the UI/AppAdmin service via the "Stop Service" menu option (note: this will logoff all existing users)
3. Edit the file /app/ui/MonTier-UI/conf/MonTierUI.conf or /app/appadmin/MonTier-AppAdmin/conf/MonTierAppAdmin.conf
4. Search for the configuration property security.limit.admin.ip

5. The property's value may contain:

   • blank - turned off, no check will be performed

   • a specific IP - like 10.0.0.9

   • an IP range surrounded with square brackets - For example 10.0.0.[100-200]  ,  10.0.[0-220].[0-255]  or  128.[10-17].0.5

   • a list of IPs and IP ranges, use comma as a separator- 10.0.0.1, 10.0.0.3, 10.0.[10-20].[0-255]

     Entering an invalid value for the security.limit.admin.ip property will prevent the service from starting

6. Save the file
7. Execute app-util.sh and start the UI/AppAdmin service via the "Start Service" menu option
