I'm hoping that using the fwmark as a selector can provide a workable
solution for both mine and Lennert's problem, any many more related
situations. Netfilter has a (almost) complete range of selectors.
e.g. Lennerts problem could be solved using a combination of the
"realm" match of iptables, in combination with a fwmark for SPD matching.
Greetings,
Ludo.
PS. On a side note: Wouldn't it be possible to have a netfilter target
stating that an transformation should be done?
