Hi Sevak,
In airBridges and aPPO, you will be
able to save 4 WEP keys. As you
said, there is no cycling selection of WEP keys in airBirdge.
We can activate only one key at a same time.
We have implemented
this option only on the aPPO in AP mode.
When airPointPRO is running on AP
mode, “Default key” selection option will not work and we use this
option for the other operational mode like client bridge mode.
In AP mode, it is capable to accept multiple WEP keys from
the multiple clients.
For example,
AP= key1 and key2
Client airBridge1= key1 and Client bridge2=key2
Both entries are already in the AP, it will pass the
traffic. As long as the access point entries matched with the key table, the
traffic will pass through.

Thanks, Sully! It will save me some restless
nights.
;-)
I'm going to look into the pppoe more closely, but probably will not implement
it for a few months.
Talking about WEP keys, I have all 4 WEP keys listed in the appo and on the
airBridges. I've just tried flipping the default key on the appo from key
1 to key 2, but lost all the airBridges. I guess the airBridges don't
have a cycling method to check for the next WEP key, huh? That would be a
nice feature, I think.
Kind regards,
Sevak

The amount of traffic
that MUST be sniffed to crack WEP is HUGE. I sniffed traffic for 72 hours
at the head-end (which hears ALL traffic on my network), and I did not receive
a single “interesting packet”. You need thousands or even
millions of “interesting packets” to crack WEP. After
successfully cracking WEP, the hacker would need to sniff the MAC and IP
pairing (not difficult), spoof them, and overpower the legitimate client so that
he drops off the network, and then you can assume his identity.
In other words….I don’t see it happening.
Don’t get me wrong…I still recommend PPPoE as
well…but I would NOT lose any sleep about someone spoofing your
customer’s MAC address.
BTW…the internal MAC authorization table (at the aPPo)
authorizes the MAC of the sB device only (not the internal MAC addresses).
I only install exterior (roof top) sB devices. So…my client
does not know their MAC address….and therefore you also don’t have
to worry about them giving their MAC address to a neighbor.
But…even if they did, the bandwidth still counts against the legitimate
client.

Hi Sully,
You're right. I am using WEP. No one has yet done this on our
network, but I would like to take preventative measures.
Thanks,
Sevak

My question is: How are they spoofing the MAC address
if you are using WEP? I highly doubt that they sniffed long enough to
break it….so are you not using WEP?
Personally…I think that it is plain old stupid to not
use WEP…unless you are running a HOTSPOT.
If you are using sB devices at the client-side, then you
just preload the WEP keys (preferably with simpleDeploy) and you are done.

I vaguely remember someone else discussing this on this list: Has anyone
come across "customers" who duplicate legitimate MAC addresses (such
as their neighbor's) on another device to get your Internet service for
free? If so, what can be done about it?
Thanks,
Sevak
