staff,
I'm a time trying to understand how an IPS can act if there is a firewall before him.
Example ..
Let's take for the Base ForeFront TMG, which is a Firewall Proxy, if I do not have any input ports opened, ie
so I exit doors open as http, https, smtp, etc., can act as an IPS on my network?
That is, if not through the Firewall, as it may have some benefit to use an IPS?
