This is a family box, and I cannot be present all the time to inspect the output. It would be better if all user accounts (as distinct from the user in the chair!) had the ability to see what the network is doing (which, most of the time would be nothing, we hope) and the human could then react if something does happen. ("If in doubt, leave it blocked and tell me what broke ")
I've long ago worked out how to get apps to work for all users, but GW seems to need UAC elevation. I've hacked all user registries to set "%user%/Software/Microsoft/Windows/CurrentVersion/Run". However, to get the system working I need to light up in Admin, switch to any other user, then log off Admin. This is a bit... kludgy. Apart from that, it's looking good.
Can we do multi-user in the program?
I'm looking to use GW in the same way I use Voodooshield, in Default Deny, and "whitelisting" the (relatively) few items that need to send out. I'm not unduly worred about inbound, I'm behind a NAT router. Working this way means the family really doesn't need to get Computer Science degrees After I've finished training GW/WF the whitelist should be 99% complete.
