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.
11. Select from 1 - 8,000. The default setting is 2,000.
12. 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 Network Configuration
Setting an access point profile’s network configuration is a large task comprised of numerous 
administration activities. 
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 8-531.
VPN Crypto Map
Use the drop-down menu to apply an existing crypt map configuration to this PPPoE interface.
