I didn't have any luck (in 24 hours anyway) with this on the general list
so now reaching out to ops and dev. Would appreciate your consideration!

Hi all,

We've got a Folsom cloud running nova-network in FlatDHCP multi-host,
currently with just a single public fixed range.

We followed
get IPv6 going (plus adding a bunch of rules allowing ICMPv6 on the
compute bridges for NDP). We've now got instances with the desired global
IPv6 addresses but are having connectivity issues, e.g., no luck ping6-ing
instances from in or outside the cloud LAN.

We started looking into possible security group issues which is when we
found this related tidbit:
"Currently, ipv6 and other protocols cannot be managed with the security
rules, making them permitted by default"

Is that correct? If it is, it seems like the kind of thing that really
ought to be mentioned in the configuration info as it's a show-stopper for
public IPv6 deployment!

Also, any tips on what might be getting in the way would be much
