+VPN Admin Module
+
+This module provides Django admin interfaces for the VPN application.
+The admin interface has been refactored into separate modules for better organization:
+
+- base.py: Common utilities and base classes
+- user.py: User management admin interface
+- server.py: Server management admin interface  
+- access.py: Access control (ACL/ACLLink) admin interfaces
+- logs.py: Logging (TaskExecutionLog/AccessLog) admin interfaces
+
+All admin classes are automatically registered with Django admin.
