"PPTP
Client
Configuration"
window
can
let
you
enable
the
PPTP
client
function
by
checking
the
"Enable"
box.
PPTP
Client
List
&
Status
"PPTP
Client
List
&
Status"
window
shows
your
defined
PPTP
clients
and
their
tunnel
connection
status.
Only
some
important
information
for
all
tunnels
are
shown
in
the
list
as
following
diagram.
Configuration
for
A
PPTP
Client
"Configuration
for
A
PPTP
Client"
window
let
you
specify
the
required
parameters
for
a
PPTP
VPN
client,
such
as
"PPTP
Client
Name",
"Interface",
"Operation
Mode",
"Remote
IP/FQDN",
"User
Name",
"Password",
"Default
Gateway/Remote
Subnet",
"Authentication
Protocol",
"MPPE
Encryption",
"NAT
before
Tunneling",
"LCP
Echo
Type"
and
tunnel
activation.
Please
be
noted
the
"Default
Gateway/Remote
Subnet"
configuration
item.
There
are
two
options,
"Default
Gateway"
and
"Remote
Subnet".
When
you
choose
"Remote
Subnet",
you
need
specify
one
more
setting:
the
remote
subnet.
It
is
for
the
Intranet
of
PPTP
VPN
server.
So,
at
PPTP
client
peer,
the
packets
whose
destination
is
in
the
dedicated
subnet
will
be
transferred
via
the
PPTP
VPN
tunnel.
Others
will
be
transferred
based
on
current
routing
policy
of
the
security
gateway
at
PPTP
client
peer.
But,
if
you
choose
"Default
Gateway"
option
for
the
PPTP
client
peer,
all
packets
will
be
transferred
via
the
PPTP
VPN
tunnel.
That
means
the
remote
PPTP
VPN
server
gateway
controls
the
flowing
of
any
packets
from
the
PPTP
client
peer.
Certainly,
those
packets
come
through
the
PPTP
VPN
tunnel.
