Scenario
Operation
Procedure
In
above
diagram,
the
Gateway
is
the
gateway
of
Network
‐
A
and
the
subnet
of
its
Intranet
is
10.0.75.0/24.
The
gateway
has
the
IP
address
of
10.0.75.2
for
LAN
interface
and
gets
a
dynamic
IP
118.18.81.33
for
WAN
‐
1
interface.
It
serves
as
a
NAT
router.
Configure
the
required
parameters
for
DDNS
function
by
referring
to
above
setup
example.
When
the
gateway
has
booted
up
and
has
gotten
a
dynamic
IP
address
for
the
WAN
interface,
the
DDNS
agent
in
the
gateway
tries
to
request
the
DDNS
server
with
the
mapping
between
the
domain
name
and
the
obtained
WAN
IP
address
of
the
gateway.
The
DDNS
server
broadcasts
the
mapping
to
other
DNS
servers
for
DNS
hosting
service
in
the
Internet
world.
So,
other
hosts
in
the
Internet
can
link
to
the
gateway
by
using
the
domain
name.
Once
the
gateway
has
dynamically
changed
its
WAN
IP
address
from
ISP,
the
DDNS
agent
tries
again
to
request
the
DDNS
server
with
the
re
‐
mapping
between
the
domain
name
and
the
new
WAN
IP
address
of
the
gateway.
The
DDNS
server
broadcasts
again
the
new
mapping
to
other
DNS
servers
for
DNS
hosting
service
in
the
Internet
world.
Finally,
other
hosts
in
the
Internet
can
still
link
to
the
gateway
by
using
the
domain
name,
even
the
WAN
IP
address
of
the
gateway
has
changed.
