I am having an issue getting ipfw to configure network delay on traffic on localhost (WinXP). I wrote a very basic batch file with the following commands

ipfw pipe 3 config delay 300ms
ipfw add pipe 3 from any to any
ping -n 4 localhost

The roundtrip time always displays 1ms though. If I ping outside sources i.e. google.com it works fine and I see a delay. Any suggestions?
