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 – 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.

Internet after passing through the time without any action.
Usually ISP dynamically assigns IP address to you each
time you connect to it and request. In some case, your ISP
provides service to always assign you the same IP address
whenever you request. In this case, you can fill in this IP
address in the Fixed IP field. Please contact your ISP before
you want to use this function.
WAN IP Alias - If you have multiple public IP addresses
and would like to utilize them on the WAN interface, please
use WAN IP Alias. You can set up to 8 public IP addresses
other than the current one you are using. Type the
additional WAN IP address and check the Enable box. Then
click OK to exit the dialog.
