I recently read that a screened subnet firewall would provide more protection from an internet attack, than an application level (proxy) firewall.
I don't understand why. Is a screened subnet firewall the same thing as a screening router?
If so, I thought a screening router is not as effective as an application level gateway / firewall, since the app level one works at the application level and also the package level (not sure what 'package' means - TCP/IP packets?) :) Thanks for any help Jason shohet
