Hi, everyone:

Does anyone know of a way to get Windows Firewall to allow access on
all ports to a specified IP address or subnet? I ask because I can
allow specific ports, but wildcards like "*" don't seem to work.

Ideally, this would be done through group policy, but any means
necessary would be a good start.

Any thoughts out there?
