We bought Zone Alarm for $19 a copy for a small 4 computer network running on a USB Hub with analog x proxy server and afer I figured out how to set up the proxy to work with it, it ran great. No fear here.. grc.com reported everything as stealth which really screws up my port scanner when I tried to scan the network from a remote location. Great product.
