A couple of comments:

o The rcp in stock FreeBSD has changed its behavior somewhere 4.7 - 4.9, to as
  you see it. It has been behaving more 'standard' way before. Self installing
  krb4 or heimdal from kth seems provides better rcp.

o How does the firewall treat backward connections ? (Ipfilter proxy ?)
  Depending on it, ports may not be properly 'diffused' (this again might
  be due to 'odd' rcp, though). As far as I can tell, rcp with said makes
  on both ends over ipfilter with r-* proxy works well (not very well,
  unfortunately).

  Closely watching FreeBSD's rcp behaviors at the connections would reveal
  something more.
