When
using
the
Intellinet
CPE
Access
Point
as
a
router,
you
will
typically
want
to
enable
the
DHCP
server
function.
Once
enabled,
the
router
provides
IP
address
information
to
the
connected
clients,
just
like
any
ordinary
router
would
do.
With
that
information,
clients
can
access
the
Internet
via
the
router.
For
information
about
the
IP
addresses,
lease,
gateway
and
DNS,
refer
to

Custom
Static
Routes
:
Static
routing
is
a
form
of
routing
that
occurs
when
a
router
uses
a
manually
‐
configured
routing
entry,
rather
than
information
from
a
dynamic
routing
protocol
to
forward
traffic.
Unlike
dynamic
routing,
static
routes
are
fixed
and
do
not
change
if
the
network
is
changed
or
reconfigured.
Static
routing
and
dynamic
routing
are
not
mutually
exclusive.
Example:
To
route
IP
traffic
destined
for
the
network
10.10.42.0/24
via
the
next
‐
hop
router
with
the
IPv4
address
of
192.168.42.1,
enter
the
following
information:
Add
Static
IP/MAC
Binding
Rules:
In
order
to
ensure
that
a
network
client
always
receives
the
same
IP
address
from
the
router,
you
can
have
the
router
assign
a
static
IP
address
to
that
client.
This
can
be
helpful
if
you
have
a
local
server
for
which
you
want
to
assign
a
static
IP
without
actually
having
to
configure
a
static
IP
address
on
the
local
server.
To
assign
a
static
allocation,
type
in
the
MAC
address
of
the
client
for
which
you
want
to
create
a
static
DHCP
lease,
and
also
type
in
the
IP
address
and
lease
time
you
wish
to
use.
Click
Add
to
create
the
static
IP/Mac
binding
rule.
If
you
want
to
make
certain
local
network
clients,
called
servers
in
this
circumstance,
accessible
from
the
Internet,
you
need
to
create
so
‐
called
port
forwarding
rules.
Without
those
rules
in
place,
the
router
would
simply
reject
any
connection
attempt
made
to
the
service
port
in
question.
For
example,
if
you
have
a
local
FTP
Server
that
is
installed
with
a
static
IP
address
of
192.168.2.100,
then
you
need
to
create
a
port
forwarding
rule
for
port
21
TCP
(Standard
FTP)
for
that
IP
address.
Now
if
a
user
from
outside
your
LAN
sends
a
request
to
the
router
on
port
21,
the
router
will
then
promptly
forward
the
request
to
IP
address
192.168.2.100.
Refer
to
the
on
‐
screen
help
for
additional
information.
DMZ
stands
for
demilitarized
zone.
You
can
activate
this
option
for
a
single
IP
address
on
your
local
network.
Once
activated,
any
traffic
sent
to
your
public
IP
address
for
any
service
port
will
be
redirected
to
the
local
IP
address
specified
as
the
DMZ
host.
If
we
apply
this
to
our
example
of
FTP
server
at
IP
192.168.2.100,
it
would
mean
that
not
only
packets
for
port
21
are
being
forwarded
to
its
IP
address,
but
any
request
on
any
port.
As
this
completely
exposes
the
local
server
on
IP
192.168.2.100
to
traffic
on
the
Internet,
that
server
is
at
greater
risk
of
being
attacked
by
hackers,
