Router
Chapter 4: Configuration
71
Example:
If
you
would
like
to
remotely
access
your
routers’
Web/HTTP
interface
all
the
time,
you
would
need
to enable
port
number
80
(Web/HTTP)
and
map
it
to
the
Router’s
LAN
IP
Address.
All
incoming
HTTP requests
on
the
WAN
network
will
then
be
forwarded
to
the
router’s
IP
address
of
10.0.0.2.
Since port
number
80
is
already
a
predefined
rule,
click
Helper
in
the
Application
section
.
A
predefined rules
window
will
pop
and
you
can
select
HTTP_Sever
.
Application: HTTP_Sever
Time Schedule: Always On
Protocol: tcp
External Port: 80-80
Redirect Port: 80-80
IP Address: 10.0.0.2
Add: Click it to apply your settings.
Edit/Delete: Click it to edit or delete this virtual server application.
I
f
you
have
disabled
the
NAT
option
in
the
WAN-ISP
section,
the
Virtual
Server
function
will
not
work
.
I
f
the
DHCP
server
option
is
enabled,
you
have
to
be
very
careful
when assigning
the
IP
addresses
of
virtual
servers
so
that
you
avoid
conflicting
IP addresses.
The
easiest
method
of
configuring
Virtual
Servers
is
to
manually assign
static
IP
address
to
each
virtual
server
Computer,
with
an
address
that does
not
fall
into
the
range
of
IP
addresses
that
are
to
be
issued
by
the
DHCP server.
These
manually
configured
IP
addresses
MUST
still
be
in
the
same subnet
as
the
route
r.
Attention
Using
port
forwarding
has
security
implications,
since
outside
users
will
be
able to
connect
to
Computers
on
your
network.
For
this
reason
you
are
advised
to add
specific
Virtual
Server
entries
only
for
the
ports
that
your
application actually
requires,
instead
of
using
the
DMZ
function.
Using
the
DMZ
f
unction will
result
in
all
connection
attempts
from
the
WAN
network
having
access
to the
public
IP
specified
in
the
DMZ
config
section
.
