Manually:
This
gateway
won’t
start
to
establish
WAN
connection
until
you
press
“Connect”
button
on
web
UI.
After
normal
data
transferring
between
LAN
and
WAN
sides,
this
gateway
will
disconnect
WAN
connection
if
idle
time
reaches
value
of
Maximum
Idle
Time.
Please
be
noted,
if
the
WAN
interface
serves
as
the
primary
one
for
another
WAN
interface
in
Failover
role,
the
Connection
Control
parameter
will
not
be
available
to
you
to
configure
as
the
system
must
set
it
to
“Auto

Scenario
:
As
an
example,
WAN
‐
1,
WAN
‐
2
and
WAN
‐
3
are
all
Ethernet
interfaces
with
"Always
on"
operation
mode.
Their
WAN
Type
is
set
to
"Dynamic
IP"
but
with
different
Connection
Control
approaches.
WAN
‐
1
uses
"Auto
‐
reconnect
(Always
on)",
WAN
‐
2
uses
"Dial
‐
on
‐
demand"
and
WAN
‐
3
uses
"Manually".
Following
3
tables
list
the
parameter
configuration
for
these
three
WAN
interfaces.
