Description of Diagram 3.0
A.
At point A, a station router has access to the Internet though a public IP address. It
has an internal IP of 192.168.1.1. It will route incoming information, destined for
192.168.2.
x
and 192.168.3.
x
to the AP's Ethernet IP address of 192.168.1.2 (subnet
mask 255.255.255.0).
B.
At point B, the AP's Ethernet IP is 192.168.1.2 (subnet mask 255.255.255.0). The
radio card has an IP of 192.168.2.1 (subnet mask) of 255.255.255.0. Incoming
information destined for 192.168.2.
x
will be delivered. The AP will route
information destined for 192.168.3.
x
to 192.168.2.2. The ESSID for the AP is TEST
and the Channel is 1. The AP wireless mode is set to
Access Point
.
•
Please Note:
The ESSID for the AP and connected CPE's
must
be identical.
If they are not, two (or more) physically separate networks will exist and
communications between these networks will not operate.
C.
At point C, the CPE's radio card IP is 192.168.2.2 (subnet mask 255.255.255.0). The
Ethernet on the CPE will have an IP of 192.168.3.1 (subnet mask 255.255.255.0).
Any information destined for 192.168.3.
x
will be routed through the CPE to the
appropriate IP address. The CPE wireless mode is set to
Infrastructure
.
D.
User machines have Ethernet IP addresses of 192.168.3.2, 192.168.3.3, etc. Each has
a gateway of 192.168.3.1.
•
Gateways: Gateways must be designated to point at the nearest portal to the
Internet. For example, at D, the gateway is 192.168.3.1. It
must
point to this
IP. If it does not point to the next nearest portal, communications will not
operate.
•
At
D
, user machines must have a gateway of 192.168.3.1 so information can
be passed to the CPE. At
C
, the radio card must have a gateway of
192.168.1.2 so information can be passed to the AP. At
B
, the Ethernet
gateway IP of the AP must have an IP of 192.168.1.1 so information can be
passed to the station router and out to the Internet.
The network implementation described above uses the AP and the CPE as routers, NOT
bridges. Configuring the hardware/software as bridges will increase the amount of
network traffic, and, as a result, will slow the network down. Configuring the
hardware/software as
routers
will decrease the amount of network traffic and will allow
for optimal performance on your network
