Yes, you can. You have some options. You can use any number of
interfaces with Linux using the name "any" for the interface
in snort, and I think also that you can use the notation eth+
to use eth0, eth1, etc. With this notation and the feature of
the command "ip" to change the name of the interfaces you can
specify a group of interfaces in snort.

The HOME_NET variable can have any number of networks, there's
no problem there.

And you can also have a snort session for each interface, with
it's own configuration files, all running in the same machine and
even logging to the same database.

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.
