Guys, sorry if I was rude before... Too much things happening at the same time today... :-P

I just installed a PFSense 2.1 with IPv6 and, for my surprise, Debian and Ubuntu Server are the only two operating systems that doesn't work "out-of-the-box" in a IPv6-Only network...

Ubuntu Desktop, Windows 7, Mac, are okay in a IPv6-Only env... Debian and Ubuntu (during the installation process, and even after) doesn't.

I mean, I tried to Install Ubuntu using the following scenarios:

1- SLAAC Unmanaged (no RDNSS) - Ubuntu Server have IPv6 addr without DNS resolution, of course (expected) - connectivity okay;

2- SLAAC Unmanaged + RDNSS - Ubuntu Server have IPv6 but no DNS name resolution (i.e. it ignore RDNSS entries from RadvD) - connectivity okay;

3- SLAAC Managed + DHCPv6 Statefull - Ubuntu Server (or Debian) get its IPv6 addr, DNS servers too but, the connectivity only starts after "ping6 my_ipv6_gateway" - NO CONNECTIVITY UNTIL PING6 GATEWAY!!

So, I'm seeing that there is no option to install Ubuntu (or Debian) in a IPv6-Only network without suffering some issues (that can be fixed after install, I know, but it is annoying). Also, we need a IPv6-Enabled NTP server too... =P

I'm okay with SLAAC-Only deployments but, huge organizations seems to require DHCPv6 for getting more info about its network services automatically and SLAAC doesn't provides it (not designed for it)...

As I said, my IPv6 router is a brand new PFSense 2.1 with "RadvD + DHCPv6 (on LAN)" and it is working fine, since I have more machines here working smoothly with IPv6 from behind it. For each scenario above, I've reconfigured PFSense to match it (Managed - Unmanaged / with - without DHCPv6).

NOTE: There is no IPv4 on this enviroment.

Best!
