IPv6 in jails

Dear Colleagues,
Is IPv6 in jails supposed to work? Does not work for me, what am I doing
wrong?
Here is a test jail:
test4 {
path = /d02/jails/test4 ;
mount.devfs;
ip4 = new;
ip6 = new;
ip4.addr = 192.168.4.204/24;
ip6.addr = 2001:470:ecba:3::4/64;
host.hostname = test4.vas.sibptus.ru ;
interface = re1 ;
allow.raw_sockets = true ;
exec.start = "/bin/sh /etc/rc";
exec.stop = "/bin/sh /etc/rc.shutdown";
}
However when I look from inside the jail, I see the daemons listening
only on IPv4:
root at test4:/ # sockstat -l
USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS
root sendmail 17178 3 tcp4 192.168.4.204:25 *:*
root sshd 17175 3 tcp4 192.168.4.204:22 *:*
root syslogd 17110 5 udp4 192.168.4.204:514 *:*
If I "ssh 2001:470:ecba:3::4" from outside, I get into the host instead
of the jail (because 2001:470:ecba:3::4 *is* assigned to re1, but not
available inside the jail).
