Not a stupid question.  Yes, you can do this.  I don't recommend putting the
server behind the firewall on your private network if you can help it.
Instead I recommend a secure third leg network that is isolated so that a
compromise of this server does not further compromise your network.  That's
the commonly accepted way of doing things.
