Leopard firewall

OS X Server 10.4 has an excellent firewall. It has a nice UI, lets you rearrange firewall rules by dragging and dropping, and is basically a sweet interface to ipfw. I haven't checked if they've made any changes or improvements on OS X Server 10.5.

What I can tell you is that it is a crying shame that Apple didn't take that nice firewall interface and put it into OS X 10.5. I understand their motivation (make it easy for Aunt Betty to feel secure) but I want more control. More at Securosis.com and Leopard firewall takes one step forward, three steps back. Alternatives are WaterRoof and DoorStop.
