5. Define the following Authentication parameters for PPPoE client interoperation:
6. Define the following Connection settings for the PPPoE point-to-point connection with the
PPPoE client:
7. Set the Network Address Translation (NAT) direction for the PPPoE configuration.
Network Address Translation (NAT) converts an IP address in one network to a different IP
address or set of IP addresses in another network. The Access Point maps its local (Inside)
network addresses to WAN (Outside) IP addresses, and translates the WAN IP addresses on
incoming packets to local IP addresses. NAT is useful because it allows the authentication of
incoming and outgoing requests, and minimizes the number of WAN IP addresses needed
when a range of local IP addresses is mapped to each WAN IP address. The default setting is
None (neither inside or outside).
Define the following Security Settings for the PPPoE configuration:
8. Use the spinner control to set the Default Route Priority for the default route learnt using
PPPoE.
Select from 1 - 8,000. The default setting is 2,000.
9. Select OK to save the changes to the PPPoE screen. Select Reset to revert to the last saved
configuration. Saved configurations are persistent across reloads.
Profile Interface Deployment Considerations
Profile Interface Configuration
Before defining a profile’s interface configuration (supporting Ethernet port, Virtual Interface, port
channel and Access Point radio configurations) refer to the following deployment guidelines to
ensure these configuration are optimally effective:
Username Provide the 64 character maximum username used for authentication support by the PPPoE
client.
Password Provide the 64 character maximum password used for authentication by the PPPoE client.
Authentication Type Use the drop-down menu to specify authentication type used by the PPPoE client, and
whose credentials must be shared by its peer Access Point. Supported authentication
options include None, PAP, CHAP, MSCHAP, and MSCHAP-v2.
Maximum Transmission
Unit (MTU) Set the PPPoE client maximum transmission unit (MTU) from 500 - 1,492. The MTU is the
largest physical packet size in bytes a network can transmit. Any messages larger than the
MTU are divided into smaller packets before being sent. A PPPoE client should be able to
maintain its point-to-point connection for this defined MTU size. The default MTU is 1,492.
Client Idle Timeout Set a timeout in either Seconds (1 - 65,535), Minutes (1 - 1,093) or Hours. The Access
Point uses the defined timeout so it does not sit idle waiting for input from the PPPoE client
and server that may never come. The default setting is 10 minutes.
Keep Alive Select this option to ensure the point-to-point connection to the PPPoE client is
continuously maintained and not timed out. This setting is disabled by default.
Inbound IP Firewall
Rules Use the drop-down menu to select a firewall (set of IP access connection rules) to apply to the
PPPoE client connection. If a firewall rule does not exist suiting the data protection needs of
the PPPoE client connection, select the Create icon to define a new rule configuration or the
Edit icon to modify an existing rule. For more information, see
Wireless Firewall .
