In order to enable PPPoE, NAT MUST be enabled on the SM, and Translation Bridging MUST
be disabled on the AP. These items will be strictly enforced for you when you are trying to enable
PPPoE. A message will indicate any prerequisites not being met. Also, the NAT Public IP DHCP
client cannot be enabled This is because the NAT Public IP will be received through the IPCP
process of the PPPoE discovery stages.
The pre-requisites required are:
• NAT MUST be enabled on the SM
o NAT DHCP Client will be disabled automatically. The NAT public IP will be received
from the PPPoE Server.
o NAT Public Network Interface Configuration will not be used and should be left to
defaults. Also NAT Public IP DHCP will be disabled if it is enabled.
• Translation Bridging MUST be DISABLED on the AP
o This will only be determined if the SM is in session since the SM won’t know the AP
configuration otherwise. If the SM is not in session, PPPoE can be enabled but if the SM
goes into session to a Translation Bridge-enabled AP, then PPPoE will not be enabled.
The following PPPoE configuration options are available:
Access Concentrator
An optional entry to set a specific access concentrator to connect to for the PPPoE session. If this
is blank, the SM will accept the first access concentrator which matches the service name (if
specified). This is limited to 32 characters.
Service Name
An optional entry to set a specific service name to connect to for the PPPoE session. If this is left
blank the SM will accept the first service option that comes back from the access concentrator
specified above, if any. This is limited to 32 characters.
Authentication Type
• None means that no PPPoE authentication will be implemented
• CHAP/PAP means that CHAP authentication will be attempted first, then PAP
authentication. The same password is used for both types.
User Name
This is the CHAP/PAP user name that will be used if CHAP/PAP authentication is selected. If
None is selected for authentication then this field is unused. This is limited to 32 characters.
Password
This is the CHAP/PAP password that will be used if PAP authentication is selected. If None is
selected for authentication then this field is unused. This is limited to 32 characters.
