space application for manipulation of the data header. It seems that 
such functionality does not exist in ipfilter, is that correct? I need 
to do this for Solaris 10/OpenSolaris. Any pointers as to where I should 
start to incorporate this capability? Or should I write a separate 
Solaris kernel module?

IPFilter only supports copying header information to user space,
the application can only return a "yes/no", it cannot change the
header or packet data in any way.
