Configuring
your
firewall
to
allow
for
a
publicly
accessible
web
server
on
your
LAN
The
predefined
port
filter
rule
for
HTTP
(TCP
port
80)
is
the
same
no
matter
whether
the
firewall
is
set
to
a
high,
medium
or
low
security
level.
To
setup
a
web
server
located
on
the
local
network
when
the
firewall
is
enabled,
you
have
to
configure
the
Port
Filters
setting
for
HTTP.
As
you
can
see
from
the
diagram
below,
when
the
firewall
is
enabled
with
one
of
the
three
presets
(Low/Medium/High),
inbound
HTTP
access
is
not
allowed
which
means
remote
access
through
HTTP
to
your
router
is
not
allowed.
Note:
Inbound
indicates
accessing
from
Internet
to
LAN
and
Outbound
is
from
LAN
to
the
Internet.
