still figuring out how to get things working on pfsense 2.1 ... able to get an external ipv6 IP but traffic is not able to reach the destinations ...

Are you getting a LAN v6 prefix ?

i'm pinging directly from the router itself .. which has a link local v6 address .. not sure if that was the problem or not,will revisit this again

XeactorZ, maybe you can try tick the "Enable IPv6" setting, save the setting and reboot the router.

Then, check back the setting page to see if you can tick the "Dual LAN". 

just try not working
I am using wifi to connect my router on my desktop
is it must connect LAN cable only can tick ?

I'm also not sure. You can try to do it.

Probably, this is the router firmware limitation. Try upgrading the router firmware, perhaps?

I am using L7 modem
I saw this 1 to update firmware
https://forum.lowyat.net/topic/2860438

from the link seems require connect LAN cable in order to update
else how ?

just tested, this ipv6 doesnt work with streamyx 512kbs or lower package with 10.x lan ip.

XeactorZ, that's the only hint i can show to you. 

I'm actually not using TM Unifi or using TM supplied modem/router at home, so i have no experience
with the L7 router.

I'm really sorry about this.

below are my config for l7 router
i can get ipv6 address for my windows 7 but not for my debian, dont know why..  
i have to put image in spoiler, lazy to resize

2 scenarios I can think of:

1) router only supports dhcpv6, doesn't support slaac. solution: install dhcpv6 client in your debian box, eg wide-dhcpv6-client or dibbler.

2) router does support SLAAC, but it is disabled in your debian kernel /proc/sys/net settings

I just heard that TMnet launched IPv6 on September 27th, so I did some experiments tonight and confirm that it is live!

[attachmentid=3654289] [attachmentid=3654290] [attachmentid=3654291]

What I've seen so far from packet dumps:
- PPP IPCP6 negotiates link-local addresses
- SLAAC Router Advertisement gives you a dynamically-assigned /64
- DHCPv6 assigns DNS servers

In addition, asellus reports that DHCPv6-PD is supported. The prefix delegated is dynamic.

DNS servers from DHCPv6:
- 2001:e68::b:68
- 2001:e68:2005:29:202:188:0:133 (does this look familiar? )

Attached is a pcap of the IPv6 assignment process.

Known working configurations:
- D-Link DSL-2730U
- D-Link DIR-615
- TP-Link WDR4300
- Mikrotik
- Windows 7 PPPoE

Just knew this news when I look at LYN's tag beside the post#xx number.
Haven't seen this post before, but then headed to: http://test-ipv6.com/ to test!
Sure enough, iPv6 is live on UniFi now!

Welcome to IPv6 land (PS: your sig is too tall, can you shorten it?)
