Broadcast Packet from AP "Not Secure"

etudes_s · 11-15-2004

Hello.
I have Problem with Broadcast Packet from AP.
i have
1 Server (X) use "AP"
3 client (A,B,C) use "AP Client"
(share internet connection)

Example:
in client A, when use "Sniffer Packet" client A always recieve Broadcast Packet from client B or C
"assume Client A,B,C are Online(use internet)"
so client A, can read the packet like(HTML,MIRC,YahooMesenger,etc)
and know what he do,like read the Client B,C email

i have many time, get the client B,C password email,ftp,etc

what should i do?
to make the Connection Secure
not broadcast,
or the packet for Client A only will arrived in Client A

any Solution?

Thank You.

Judging by the overwhelming response, I'm guessing no.

Let me try to put this in plain English.

You have an Acesss Point and there are 3 clients using it.
When you're on client A running let's say Ethereal you can see the packets from clients B and C

Doesn't sound like anything is wrong if the were 20 clients you'd be able to see all the traffic (packets) that's what packet sniffers do. Unless you have each client running through a VPN tunnel or some other secure method you'll be able to see the data transfer.

So
it mean Imposible to make a Connection that the packet for Client A only will arrived in Client A ??

i mean, Can AP function Like "SWITCH" (packet only directed in one address)
not function like "HUB"
???

Thank You.

Sorry , but AP's are "hubs".

The packet is only directed for one address but because you're using a packet sniffer your putting the card into a mode were its being told to look at all the packets not just the ones that are addressed to it.

Doesn't HyperWRT have a feature where you could setup each AP user in an 'isolation' mode where they don't 'see' each other?

I realize with airodump, LinkFerret, Aeropeek or any other 'RF' sniffer, you're still going to see the packets.

I'll have to get a spare laptop and do some testing tonight.

I think that they had a V-Lan mode. You could block the sharing ports.

That's what I'm trying to figure from the poster. If they understand how networks work and what a packet sniffer is doing. Maybe they really do want isolation between clients.

I'm guessing NO...maybe the genius is confusing a "broadcast packet" with the fact that the AP is broadcasting the SSID. That being the case, we're all wasting our time.
