WAN
&
Uplink
The
gateway
provides
multiple
WAN
interfaces
to
let
all
client
hosts
in
Intranet
of
the
gateway
access
the
the
uplink
network
or
Internet.
But
ISPs
in
the
world
apply
various
connection
protocols
to
let
gateways
or
user's
devices
dial
in
ISPs
and
then
link
to
the
Internet
via
different
kinds
of
transmit
media.
So,
the
WAN
Connection
lets
you
specify
the
WAN
Physical
Interface,
and
WAN
Internet
Setup
for
Intranet
to
access
Internet.
For
each
WAN
interface,
you
must
specify
its
physical
interface
first
and
then
its
Internet
setup
to
connect
to
uplink
network
or
Internet.
