Connection
Name:
A
user-defined
name
for
the
connection
(e.g.
“connection
to
office”).
Type:
Select
Dial
Out
if
you
want
your
router
to
operate
as
a
client
(connecting
to
a
remote
VPN
server,
e.g.
your
office
server),
select
Dial
In
if
you
want
your
router
to
operate
as
a
VPN
server.
When
configuring
your
router
as
a
Client,
enter
the
remote
Server
IP
Address
(or
Domain

you
wish
to
connection
to.

in
User
address.
Username:
If
you
are
a
Dial-Out
user
(client),

the
username
provided
by
your
Host.
If
you
are
a
Dial-In
user

PPP
Authentication
Type:
Default
is
Auto.
This
is
the
correct
setting
if
you
want
the
router
to
determine
which
authentication
type
to
use,
or
else
you
can
manually
specify
CHAP
(Challenge
Handshake
Authentication
Protocol)
or
PAP
(Password
Authentication
Protocol)
if
you
know
which
type
the
server
is
using
(when
acting
as
a
client)
When
acting
as
a
server,
specify
the
authentication
type
you
want
clients
connecting
to
your
router
to
use.
When
using
PAP,
the
password
is
sent
unencrypted,
whilst
CHAP
encrypts
the
password
before
sending,
and
also
allows
for
challenges
at
different
periods
to
ensure
that
an
intruder
has
not
replaced
the
original
client.
Data
Encryption:
Data
sent
over
the
VPN
connection
can
be
encrypted
by
an
MPPE
algorithm.
Default
is
Auto
and
this
means
that
this
setting
is
negotiated
when
establishing
a
connection.
Alternatively,
you
can
manually
Enable
or
Disable
encryption.
Key
Length:
The
data
can
be
encrypted
by
MPPE
algorithm
with
40
bits
or
128
bits.
Default
is
Auto
which
means
that
it
is
negotiated
when
establishing
a
connection.
128
bit
keys
provide
stronger
encryption
than
40
bit
keys.
Mode:
You
may
select
Stateful
or
Stateless
mode.
The
key
will
be
changed
every
256
packets
when
you
select
Stateful
mode.
If
you
select
Stateless
mode,
the
key
will
be
changed
in
each
packet.

Auto-disconnect
the
VPN

for
a
predetermined

means
this
connection
is
always
on.
Active
as
default
route
:
If
you
select
this
option
while
using
Dial-out
connection,
all
packets
will
route
through
the
VPN
tunnel
to
the
Internet;
therefore,
activating
the
function
may
degrade
Internet
performance.
