[Openswan Users] Encrypt IPv6 multicast addresses

[Nuno Amorim]

Hello list!

I was looking at the mailing list archive and did not find anything
about this issue.

I want to encrypt an IPv6 UDP stream that has a multicast destination
address (like ff1e::5). The preference is with tunnel mode, with AES
128bit ESP and preshared keys.

Looking for a solution about the key exchange, I stumbled in RFC 3830
(Multimedia Internet Keying), which I think is a solution (or part of)
for the encryption of one to many flows.

So, does anyone tried anything like this? Does Openswan support this
type of tunnel?

Thanks for the help.
