IP-852 Device Ports
The IP-852 device uses IANA designated ports for L

traffic (ports 1628 and
1629). Continuing with the example described above, you could connect an IP-852 device
to your network with an IP address of 192.168.1.102.

Figure 4.4 Adding an IP-852 Device to an NAT Gateway
To allow Internet access to your IP-852 device, you must map the necessary ports on
your NAT gateway (as you did for the computers when setting up Web access). Once port
1628 is mapped to 192.168.1.102, the NAT gateway will forward any requests from peer
IP-852 devices or from the IP-852 Configuration Server.
IP-852 devices can be configured to use ports other than the IANA defaults. This allows
multiple IP-852 devices to reside behind a single NAT gateway. The default Web server
port for a SmartServer or i.LON 600 server is 80. In the example, port 80 is already used
by 192.168.1.100, so you must change the port on the IP-852 device and enter two static
mappings into the NAT gateway:
Port 1628 Æ 192.168.1.102
Port 82 Æ 192.168.1.102
Consult your NAT gateway documentation for details on how to setup static port
mapping for your particular NAT gateway.

ORKS
networks that do not connect to an IP network may be quite large. A
L
ON
W
ORKS
network may contain 255 subnets, with each subnet containing as many as
127 devices. Subnets are linked together using L

ORKS
routers. A common
implementation is to have many FT subnets connected to a single TP/XF-1250 high
speed backbone.
