Seamless
Failover:
In
addition,
there
is
a
"Seamless"
option
for
Failover
operation
mode.
When
seamless
option
is
activated
by
checking
on
the
"Seamless"
box
in
configuration
window,
both
the
primary
connection
and
the
failover
connection
are
started
up
after
system
rebooting.
But
only
the
primary
connection
executes
the
data
transfer,
while
the
failover
one
just
keeps
alive
of
connection
line.
As
soon
as
the
primary
connection
is
broken,
the
system
will
switch,
meaning
failover,
the
routing
path
to
the
failover
connection
to
save
the
dial
up
time
of
failover
connection
since
it
has
been
alive.
When
the
“Seamless”
enable
checkbox
is
activated,
it
can
allow
the
Failover
interface
to
be
connected
continuously
from
system
booting
up.
Failover
WAN
interface
just
keeps
connecting
without
data
traffic.
The
purpose
is
to
shorten
the
switch
time
during
failover
process.
So,
when
primary
connection
is
disconnected,
failover
interface
will
take
over
the
data
transfer
mission
instantly
by
only
changing
routing
path
to
the
failover
interface.
The
dialing
‐
up
time
of
failover
connection
is
saved
since
it
has
been
connected
beforehand.
VLAN
Tagging
Sometimes,
your
ISP
required
a
VLAN
tag
to
be
inserted
into
the
WAN
packets
from
Gateway
for
specific
services.
Please
enable
VLAN
tagging
and
specify
tag
in
the
WAN
physical
interface.
Please
be
noted
that
only
Ethernet
and
ADSL
physical
interfaces
support
the
feature.
For
the
device
with
3G/4G
WAN
only,
it
is
disabled.
