5 - 56 WiNG 5.5 Access Point System Reference Guide
6. Define the following Authentication parameters for PPPoE client interoperation:
7. Define the following Connection settings for the PPPoE point-to-point connection with the PPPoE client:
8. 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 router 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).
9. Define the following Security Settings for the PPPoE configuration:
10. 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.
11. 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.
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.
Use the Show option to view the actual characters comprising the password.
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 on page 8-2.
VPN Crypto Map Use the drop-down menu to apply an existing crypt map configuration to this PPPoE
interface.
