Install Network Policy Server

You can use this topic to install Network Policy Server (NPS) by using either Windows PowerShell or the Add Roles and Features Wizard. NPS is a role service of the Network Policy and Access Services server role.


By default, NPS listens for RADIUS traffic on ports 1812, 1813, 1645, and 1646 on all installed network adapters. If Windows Firewall with Advanced Security is enabled when you install NPS, firewall exceptions for these ports are automatically created during the installation process for both Internet Protocol version 6 (IPv6) and IPv4 traffic. If your network access servers are configured to send RADIUS traffic over ports other than these defaults, remove the exceptions created in Windows Firewall with Advanced Security during NPS installation, and create exceptions for the ports that you do use for RADIUS traffic.
