I have set up a few radios to test the feasibility of a link for joining a
customer's two sites together.  Due to non line of sight between the two
buildings, a relay site has to be used.  The radios at the relay site will
be connected using a hub (eventually to be replaced by a switch).

When using simpleNMS on PC2 (connected to the airBridge @ Site B), all the
radios in the chain can be seen.  When using simpleNMS on PC1 (connected to
the aPPO Access Point @ Site A), only the aPPO 1 (Access Point IP
192.168.168.26) can be monitored.  However, the MAC address of aPPO 2
(Client Bridge IP 192.168.168.27) shows up as a client in simpleNMS, with
the LQ and RSSI values registering in the Client Info tab.

I am able to ping all IP's from PC2 @ Site B, but only aPPO 1 from PC1 @
Site A.

Am I missing something basic here?  Why would all radios appear when looking
from one end of the "chain", but not from the other? I want to change the
first link (or maybe both) to a Wireless Bridge but would like to find what
the issue is here first!

Any ideas would be greatly appreciated.


The equipment at each location is as follows:

Site A: 1 x aPPO
Relay site: 1 aPPO, 1 x aPPTotal, 1 x 10Mbps hub
Site B: 1 x aBTotal

...and the topology and IP addresses are as follows:

PC1 @ Site A - IP: 192.168.168.201/24 GW: 192.168.168.100
 |
 |
aPPO 1 (AP mode) @ Site A - IP: 192.168.168.26/24 GW: 192.168.168.100
 .
 .
aPPO 2 (CB mode) @ Relay Site - IP: 192.168.168.27/24 GW: 192.168.168.100
 |
 |
10Mbps hub @ Relay Site
 |
 |
aPPTotal 1 (AP mode) @ Relay Site - IP: 192.168.168.30/24 GW:
192.168.168.100
 .
 .
aBTotal 1 @ Site B - IP: 192.168.168.60/24 GW: 192.168.168.100
 |
 |
PC2 @ Site B  - IP: 192.168.168.100/24 GW: 192.168.168.100


. = wireless link
| = cabled link

I hope the topology makes sense - the line lengths may get trimmed by your
email client causing a linefeed to be inserted.
