portscan preprocessor and external net

[marco turr <marco_syslnx () yahoo it>]

  Hi,
  I have a problem with portscan preprocessor.
  I need to detect scan from $home -> $home and scan from $home -> any.
  I see that in sfportscan and flow-portscan preprocessor there are options like src-ignore-net or ignore-scanners.
  Now if i set one of this options at $EXTERNAL_NET (where  EXTERNAL_NET is !$HOME_NET) i get an error.
  How can i resolve this?
  Thanks a lot
