You do seem to be hell bent on spending good money on this when the best solution is to get hold of a piece of junk somebody has thrown out and put a second NIC in it. It will give you a choice of almost any Linux version to run on it and a choice of any decent open source firewall (eg, IPcop). You can quickly get to the situation where nobody can as much as sneeze on your LAN or WAN without you knowing about it. You can also police the whole thing and allow/disallow anything you want.
