3.6 How can I run Snort on multiple interfaces simultaneously?

LINUX: If you aren't running snort on linux 2.1.x/2.2.x kernel (with LPF available) the only way is to run multiple instances of snort, one instance per interface (with the -i option specifying the interface). However for linux 2.1.x/2.2.x and higher you can use libpcap library with S. Krahmer's patch which allows you to specify 'any' as interface name. In this case snort will be able to process traffic coming to all interfaces.

*BSD: Use the ``bridge'' interface to combine your nics into a logical interface (bridge0).
