IPsec v3 question

[Alan Stultz]

Hello All:
 
I have a question about the implementation of IPsec version 3 in FreeBSD.
We are porting from FreeBSD 5.4 to 7.2 and currently run an IPv6 application
with IPsec version 2 and IKEv1 open source from the KAME group.  Since the
KAME group disbanded (around when 5.4 was released), I don't know what RFCs
for IPsec and IPv6 are currently implemented in various FreeBSD releases.
I'm most interested in the following:
 
RFC4301 - Security Arch. for the Internet Protocol
RFC4302 - IP Authentication Header
RFC4303 - IP ESP
RFC4308 - Cryptographic Suites for IPsec
 
If anyone has a list or knowledge of the latest IPv6 RFCs supported in
FreeBSD, I would appreciate any info on them.

Thanks in advance,
Alan
