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.

this box, PCs on the same wireless network can use another
set of PPPoE session (different with the Host PC) to access
