What do you mean they're "tappable"?
What, exactly, do you know about running an IP based network? Do you run one, I do.
YOu tell me how to "tap" a multipath, multihome, dynamicly routed network, with NO physical media between routers.
That's right, I run a WIRELESS network, that has no physical connections... EXCEPT at the customer's computer, and at the border gateway(s), with multiple paths out and in from each host.
You still don't get it. I guess I'll start a new thread, and this time try to explain it down to baby steps, since nobody seems to want to think... (sigh).
your network is wireless to a point. at some point, it comes off the air to an access point - that has physical connections - that can be bridged and sniffed.
I tap and monitor wifi hosts on my network all the time. What are you talking about?
