More of a theoretical question really... as I am already behind a router with firewall, if I was to disable Internet Filtering - would the Application Filtering still work OK, and only the programs that I allowed would be able to connect out (and in) ? Are any rules in the standard ruleset made redundant because I am behind a router, and what would be the worst that could happen if I was to disable Internet Filtering ? I was really just wondering about this, but couldn`t really get a good understanding of how closely linked they are to each other. I was under the impression that Application Filtering alone would be enough to block unwanted programs from connecting out, and the router would take care of unwanted things coming in ? Probably totally wrong, but just needed some clarification about what would happen and how crucial Internet Filtering actually is behind a router.
