If your IDS is reading directly from network interface (like network
sniffers such as tcpdump or ethereal do), than it bypasses the firewall.
You'd need to configure your IDS software to ignore whatever you
consider "normal" traffic on your network. But be warn, the more you
ignore, the less you see.
