Breakage noticed when debian upgraded to xtables (iptables > 1.4.1)
Many thanks to Yevgeny Kosarzhevsky <yevg@pisem.net> for reporting
and a lot of testing
Thanks to Jan Engelhardt <jengelh@medozas.de> for a lot of advice
Thanks to Denys Fedoryschenko <denys@visp.net.lb> for some sample
code that he tried and thanks to Andreas Henriksson <andreas@fatal.se>
(who maintains iproute2 on debian) for the persistent followup.
