Just use:
INTERFACE=any

But you have to change the script. What it's wrong it's the script
you are using. It specifies the variable INTERFACE but it doesn't
use it later to launch snort, so it won't work.

Change the line:
daemon /usr/local/bin/snort -u snort -g snort -d -D \
                -c /etc/snort/snort.conf

to:

daemon /usr/local/bin/snort -u snort -g snort -d -i $INTERFACE -D \
                -c /etc/snort/snort.conf

and it will work.

The only people for me are the mad ones -- the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn, burn
like fabulous yellow Roman candles.
