I solved the problem, enhancing a little the "expr" command: now it
is able to to logical bitwise operation such

                # expr 4 & 255
                # expr ~ 4

etc (must quote \&, \~).
After that, I changed the ip_network and the ip_broadcast AWK script,
calling the external program expr (ugly, but awk do not seems to
support this kind of C language operation).

The theory used (if I'm not wrong) is:

                network= ip & mask
                broadcast = ip | ~mask

I've the ipfix.tgz (only 13k) and send to you now via attachment.
In the archive, also the new busybox (for the expr).
