# PPPoE Configuration

You can configure a specific instance of PPPoE with a user name and password and other parameters, and bind the instance to an interface.

### To Configure a PPPoE Instance

PPPoE Instance: Enter the name of the instance. Choose a descriptive name to help you identify the instance.

Enable: Select the checkbox to enable PPPoE.

Bound to Interface: Select the interface to which you want to bind the PPPoE instance.

Username: Enter the user name for the PPPoE connection.

Password: Enter the password for the PPPoE connection.

Authentication: Select the authentication method.

Any means both CHAP and PAP authentication are used.

CHAP means only CHAP authentication is used.

PAP means only PAP authentication is used.

Access Concentrator: TEXT needed

Service: TEXT needed

Default Route Metric: Specifies the default route metric (cost) for PPPoE sessions.

Netmask: Specifies a subnet mask for the protected network.

Auto-Connect option specifies the number of seconds before a previously-closed connection is automatically reinitiated. Specify a value between 0-10000. A value of 0 disables this function.

Clear IP on Disconnect: Select the checkbox if you want the device to clear the IP address of the host when the device is disconnected from a PPPoE host.

Static IP: Select the checkbox to enable the connection to use the IP address that was assigned to the device's interface.

Automatic Update of DHCP Servers DNS Parameters:When you initiate a PPPoE connection, your ISP automatically provides the IP addresses for the Untrust zone interface and the IP addresses for the Domain Name System (DNS) servers. Select this checkbox if you want the device to overwrite the local settings with the DNS settings it receives through PPPoE.
