VPN
VPN(Virtual
Private
Network)
is
mainly
used
for
setting
up
long
‐
distance
and/or
secured
network
connections.
When
used
on
CooVox
IPPBX,
all
phone
calls
made
and
received
are
encrypted
so
it
secures
your
remote
offices/extensions'
phone
services.
Built
‐
in
VPN
Server
on
CooVox
series
is
an
easy
way
to
set
up
a
secured
connection
between
other
CooVox
series
IPPBXs
or
IP
phones.
You
don't
need
to
build
a
dedicated
VPN
server
or
buy
a
VPN
router.
This
is
also
a
workaround
to
avoid
firewall
issues
when
configuring
remote
VoIP
client
such
as
SIP
protocol
which
is
notoriously
difficult
to
pass
through
a
firewall
due
to
its
random
port
numbers
to
establish
connection.
CooVox
IP
PBX
supports
four
varieties
of
VPN,
they
are
L2TP,
PPTP,
OpenVPNandIPSec.
5.3.1
L2TP
VPN
L2TP
VPN
Server
Layer
2
Tunneling
Protocol
(L2TP)
is
a
tunneling
protocol.
It
does
not
provide
any
encryption
or
confidentiality
by
itself.
Rather,
it
relies
on
an
encryption
protocol
that
it
passes
within
the
tunnel
to
provide
privacy.
Here
on
the
CooVox
IPPBX
system
we
useIPSec
to
do
the
encryption.
To
configure
your
L2TP
server,
navigate
to
web
menu
Network
Settings
‐
>VPN
Server
.
Check
the
radio
button
of
L2TP
to
configure
L2TP
VPN
server.
