Updating existing firewall rule using API

Question

I am able to pro grammatically add individual rules to the Windows Firewall (Server 2008 R2), however I am trying to avoid multiple rules per IP address, and would just like to

Answer 1

The code below works for me:

INetFwPolicy2 firewallPolicy = (INetFwPolicy2) Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwPolicy2"));

var rule = firewallPolicy.Rules.Item("Block Bad IP Addresses"); // Name of your rule here
rule.Name = "Block Block Block"; // Update the rule here. Nothing else needed to persist the changes
