2.3.99-pre5 netfilter -j REDIRECT broken

Hi Paul & all,

the port redirection in the -preX netfilter code seems broken.
I fixed redirect_target() to also use the multirange struct,
and then found strange things with the port byte order.
See the attached diff - applied to -pre5 it works now (tested for
the case of capturing remote connections to local ports; without
the patch they do go to localhost, but keep the original port
instead of using the --to-port).

Exhibit B shows syslog output for the nonworking case (already using
multirange), Exhibit C shows the working case (with this patch applied).

regards
  Patrick

to other people. Please Cc: me on discussions)
