PPPoE Configuration
PPPoE (Point-to-Point over Ethernet) is a network protocol which encapsulates PPPoE
frames into Ethernet frames. The router uses the PPPoE client to connect to devices support-
ing a PPPoE bridge or server. The bridge or server is typically an ADSL router.
To open the
PPPoE Configuration
page, select the
PPPoE
menu item. If you mark the
Create PPPoE connection
check box, then the router attempts to establish a PPPoE connec-
tion after boot up. After connecting, the router obtains the IP address of the device to which
it is connected. The communications from a device behind the PPPoE server is forwarded to
the router.

MRU
Specifies the Maximum Receiving Unit. The MRU identifies the max-
imum packet size, that the router can receive in a given environ-
ment. The default value is 1492 bytes. Other settings can cause in-
correct data transmission.
MTU
Specifies the Maximum Transmission Unit. The MTU identifies the
maximum packet size, that the router can transfer in a given envi-
ronment. The default value is 1492 bytes. Other settings can cause
incorrect data transmission.

Setting a bad packet size value (MRU, MTU) can cause unsuccessful transmission.
