cloning traffic with iptables

[sbuhlig at gmail.com (Sam Buhlig)]

You can buy cards that will do it on wired. The one area I would be careful
about is if it has fail over or not. If it does not have fail over then you
could have a real problem if that machine lost power or needed maintenance,
considering it has to be hooked to the main line. Just something to
consider. Don't know how it would apply going wireless. Best of luck.
