The router offers PPPoE dial-up connection. Besides, you
also can establish the PPPoE connection directly from local
clients to your ISP via the Vigor router. When PPPoA protocol
is selected, the PPPoE package transmitted by PC will be
transformed into PPPoA package and sent to WAN server.
Thus, the PC can access Internet through such direction.
For Wired LAN – If you check this box, PCs on the same
network can use another set of PPPoE session (different with
the Host PC) to access into Internet.
For Wireless LAN – It is available for n model. If you check
this box, PCs on the same wireless network can use another
set of PPPoE session (different with the Host PC) to access
into Internet.
Note: To have PPPoA Pass-through, please choose PPPoA
