[sentinix-list] Sentinix with two nics

Can you set up Sentinix with two nics?  I have one connected directly to a
span nic on my openbsd transparent bridge.  This does not have inet access
so I need to use a second nic to connect to this box.  Question is, can I
set the first nic up so that it just istens and captures all the data sent
through the span and then have the second nic for connecting?  The first nic
wouldn't need an ip.
