PPPoE Pass-through The modem offers PPPoE dial-up connection. Besides, you
also can establish the PPPoE connection directly from local
clients to your ISP via the Vigor modem. 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.
