Subject: 6to4/Teredo IPv4 matching

Are there any plans to allow matching 6to4/Teredo IPv6 packets against IPv4
rules (or at least ipsets)? Recently I have a server that's been under
constant DDoS from China, and I found that when I use ipsets to drop
everything from China, some continue to hammer my server over 6to4 and/or
Teredo. So I just figured I'd throw the idea out there in case it hasn't
occurred to anyone yet. ;)

ipset 5 is about to be released in this week, with both IPv4 and IPv6
support. But feeding the sets with the proper addresses/networks is left
to the users :-).

Best regards,
