Re: Alternative ways of IP spoofing?

[thenetdr () YAHOO COM (John D. Burkett)]

If host "x" is on the same IP Network, I don't think
the router would be a concern as there would likely
not be the same ip network on more then one of the
routers interfaces.

Some switches have options to block stuff tho, but
it's not too common to find that feature used on a
small LAN.

It seems odd to ask if Computer Security is ethical.  We are in fact comfortable with what we are doing, but that is 
because we have asked the question of ourselves, and then answered it to our own satisfaction.  Sed Quis Custodiet 
ipsos custodes? -from "repelling the wily hacker".
