Once the bits and status LEDs align (
green-amber-green in Figure 2), Screenshot 3 appears. Since we will be
accessing the Communications Gateway using an Internet
connection, we will need to configure a static IP address
and assign our desired Dialin TCP socket port. These
adjusted configuration values must match the
configuration values that exist in the router that is serving
I’ve decided to assign the ZigBee
Gateway a static IP address of
192.168.0.97 with a port number of
8800. Scanning Screenshot 4 reveals the
disabling of DHCP and defining the LAN
default Gateway IP address in addition to
assigning the TCP socket values
(192.168.0.97:8800). For this magic to
work, we must also configure the LAN

■ Screenshot 3. Note the default Static IP Configuration
and Dialin TCP Sockets Configuration values. We will deal
with them later. The important thing right
now is that DHCP is enabled by default and
we can view this web page.
■ Screenshot 4. This is a view of the ZigBee
Communications Gateway's Configuration web page.
These values have nothing whatsoever to do with the
ZigBee module configuration.
■ Screenshot 5. The router has been configured to allow traffic to pass to and
from the 192.168.0.97:8800 socket interface.
■ Screenshot 6. The
dynamic DNS service
is much cheaper than
leasing a static IP from
an ISP. The DynDNS
service keeps track of
the LAN router's
address, which is
changed by the ISP.
