Re: [Snort-users] Capture Email Content / Website Activity

I would like to revise my question.

The first scenario:
Internet --> Modem --> snortbox --> router --> local network
will not allow me to specify what machine is sending information. It would 
just give me the ip of the router. Right?

The second scenario:
Internet --> modem --> router --> snortbox --> switch --> local network
this scenario will allow me to monitor the activity from within the local 
network.

Is scenario 2 correct?

In the second scenario is it nessicary to run iptables or is iptables used to 
route the traffic?

Also I do see the value of squid to monitor the traffic to the web.

Thanks.
