  Modified files:
    sbin/ipfw            ipfw.8 ipfw.c 
    sys/netinet          in.h ip_fw.c ip_fw.h ip_input.c 
                         ip_output.c ip_var.h tcp_input.c 
  Log:
  Support for IPFW based transparent forwarding.
  Any packet that can be matched by a ipfw rule can be redirected
  transparently to another port or machine. Redirection to another port
  mostly makes sense with tcp, where a session can be set up
  between a proxy and an unsuspecting client. Redirection to another machine
  requires that the other machine also be expecting to receive the forwarded
  packets, as their headers will not have been modified.
  
  /sbin/ipfw must be recompiled!!!
