I suppose you're nmap'ing on the same host you configured snort to listen on
(e.g. eth0 with linux). Either configure snort to listen on the loopback
device (lo with linux) and namp localhost, or use another station in your
network to nmap your snort box. Make sure you don't have preprocessor
portscan-ignorehosts or portscan2-ignorehosts configured to ignore your nmap

If your snort box is listening on a switch make sure to use a mirror/SPAN
port to receive all the traffic you expect it to receive.
