Could I suggest in future that you start a new thread rather than bumping an old one with a lot of largely irrelevant information to read through?
config snort 'lan' option interface 'eth0:eth1:eth2:eth3:eth4:eth5' option config_file '/etc/config/snort.conf'
procd_set_param command $PROG "-de" "-Q" "-i" "$device" "--daq" "afpacket" "--daq-dir" "/usr/lib/daq/" "-c" "$config_file"
You could also create a new interface which is software bridge over all those ethernet interfaces and then use that single software bridge in the snort command instead. It will probably be more efficient.
