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. ;)
