You have to start individual instances of snort
to sniff each of your interfaces, ie separate
snort process should be run for each NICs like
eth0, eth1 etc..

Example;
snort -i eth0 -c /etc/snort/snort.conf
snort -i eth1 -c /etc/snort/snort.conf
....it goes on

N.S: When running in more than one interface, it's
better to start snort in background (-D option).
