New Revision: 278324

Log:
  MFC 277714:
  natd(8) will work with an unconfigured interface and effectively not do
  anything until the interface is assigned an address.  This fixes
  ipfw_nat to do the same by using an IP of INADDR_ANY instead of
  aborting the nat setup if the requested interface is not yet configured.
