This screen varies according to the type of encapsulation you
select.

the field My WAN IP Address.
PPPoE Pass
Through
(PPPoE
encapsulation
only)
This field is available when you select PPPoE encapsulation.
In addition to the Business Secure Router built-in PPPoE client, you
can enable PPPoE pass through to allow up to ten hosts on the LAN
to use PPPoE client software on their computers to connect to the
ISP using the Business Secure Router. Each host can have a
separate account and a public WAN IP address.
PPPoE pass through is an alternative to NAT for applications where
NAT is not appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the
LAN to use PPPoE client software on their computers to connect to
the ISP.
