Ste Jones submits By using openBSD's packet filter pf one can utilize the NAT address pools added into OpenBSD 3.3 to aid in distributed port scanning. As the text explains NAT can be used in a large network to split outgoing connections over multiple source IP addresses. Under normal circumstances NAT is normally used to hide a internal network behind a single external public IP address. By using multiple external IP addresses a host on the internal network can port scan with multiple source IP's.
