PPPoE Server

pfSense® software can act as a PPPoE server, accepting and authenticating connections from PPPoE clients on a local interface, in the role of an access concentrator (LAC). This feature can be used to force users to authenticate before gaining network access, or otherwise control their login behavior.

The PPPoE Server is located at Services > PPPoE Server. The configuration is very similar to the L2TP VPN server (L2TP VPN).

Multiple PPPoE servers may be configured on separate interfaces. To begin setting up a PPPoE server:

  • Navigate to Services > PPPoE Server

  • Click fa-plus Add to add a new server entry

  • Configure the PPPoE Server as follows:


    When checked, this PPPoE Server instance will be active.


    The single interface upon which PPPoE service will be available.

    Total User Count

    Determines how many clients in total are allowed to connect to this instance.

    User Max Logins

    Determines how many times a single client may login concurrently.

    Server Address

    The IP address which the pfSense system will send to the PPPoE clients to use as their gateway.


    This IP address must not be an IP address currently in use on the firewall.

    Remote Address Range

    The IP address for the start of the PPPoE client subnet. Together with the Subnet Mask it defines the network used by the PPPoE clients.

    Subnet Mask

    Defines the CIDR mask assigned to PPPoE clients.


    Optional explanatory text for this server instance.

    DNS Servers

    Optional fields used to send specific DNS servers to the PPPoE clients, otherwise the firewall IP address will be sent to the client for DNS if the DNS Forwarder or DNS Resolver are enabled. If the DNS Forwarder and DNS Resolver are both disabled, then the DNS servers configured on the firewall will be sent instead.

  • Configure RADIUS if that will be utilized for user authentication. Any RADIUS server may be used.

    See Authenticating from Active Directory using RADIUS/NPS for information on setting up RADIUS on a Windows server.

    Use RADIUS Authentication

    Check to configure the PPPoE server to use at least one RADIUS server for Authentication instead of local users.

    Use RADIUS Accounting

    Optional, sends RADIUS accounting data to the RADIUS server to note items such as login and logout times, and bandwidth used.

    Use a Backup RADIUS Authentication Server

    A second RADIUS server to use if the primary RADIUS server fails.

    NAS IP Address

    Optional, sends a specific IP address to the RADIUS server for the NAS-IP-Address attribute.

    RADIUS Accounting Update

    The interval at which accounting data is sent to the RADIUS server, in seconds.

    RADIUS Issued IP Addresses

    When checked, IP addresses can be assigned to users via RADIUS reply attributes.

    Primary RADIUS Server

    The preferred RADIUS server to use for Authentication.

    IP Address

    The IP address of the RADIUS server

    Authentication Port

    The port used for authentication (typically 1812)

    Accounting Port

    The port used for accounting data (typically 1813)

    Primary RADIUS Server Shared Secret

    The shared secret configured for this firewall on the RADIUS server. The same value must be entered in the Confirm box.

    Secondary RADIUS Server

    Same type of settings as the primary, but defines the secondary RADIUS server.

  • Add users to the server to utilize local authentication:

    • Click fa-plus Add User


    The username for the user account


    The password for the user account

    IP Address

    An optional static IP address to assign the user at login

    • Repeat as needed
