Windows Firewall

Hi,

I’m trying to create Windows Firewall rule(s) and then populate them using GPOs to achieve the following:

1. Block all inbound traffic to nodes in the OU from specific networks.

2. Prevent specific nodes in the OU from applying “Block all” GP

3. On nodes excluded from “Block all” GP allow inbound traffic coming from specific networks only on specific ports.

Ad 1. Easy to do

Ad 2. Easy to do using GP Delegation

Ad 3. Have no idea how to achieve this.

Any help would be much appreciated.
