windows firewall - allowing all ports for a trusted subnet

I am trying to allow all inbound traffic from a specific subnet using the
built-in windows firewall. I've poked around both the GUI and 'netsh
firewall' interface, but neither seem to allow wild cards for opening all
ports on a specified subnet.

Does anyone know a of a secret wild card, or am I stuck with unlocking every
single port for my trusted subnet?

Hi Ryan,

My solution for this would be to use IP Filter (IPSec Filters) for this. If
you have Active Directory environment you can even use Group Policy do
deploy these filters to all your computers.

Here is an example on how IP Filters are created. It is practically the same
on Windows XP and Windows 2003.
