Procedure
In
above
diagram,
Network
‐
A
is
in
the
headquarters,
and
the
subnet
of
its
Intranet
is
10.0.76.0/24.
The
security
gateway
for
Network
‐
A
has
the
IP
address
of
10.0.76.2
for
LAN
interface
and
203.95.80.22
(or
FQDN:
www.abc.com
)
for
WAN
interface.
However,
Network
‐
B
is
in
the
mobile
office
and
the
subnet
of
its
Intranet
is
10.0.75.0/24.
The
security
gateway
for
Network
‐
B
has
a
dynamic
IP
address
of
118.18.81.33
for
WAN
interface
or
private
IP
address
of
10.253.253.1
in
Cellular
Network
.Establish
an
IPSec
VPN
tunnel
with
"Dynamic
VPN"
scenario
by
starting
from
the
mobile
site.
So
both
Intranets
of
10.0.75.0/24
and
10.0.76.0/24
can
securely
communicate
each
other.
Finally,
the
client
hosts
in
the
Intranet
of
Network
‐
B
at
mobile
office
can
access
