Ipv6 address problem
-
my isp (otenet.gr) offers dual stack and i read that on some router modem (hawei,zte) it works with slaac and i fritz! it uses dhcp6.
When i try dhcp6, my wan interface shows as a ipv6 address fe80::xxx%re1 with mac address of the ethernet that connects to my adsl modem.
when i try slaac, my wan interface shows no ipv6 address.My Diagnostics: Routing tables for my ipv6 is

fe80:: is link-local. Not sure what you read but your ISP does not seem to deliver any IPv6 whatsoever no matter what.

hmm wierd, because from shell i can ping and traceroute ipv6 addresses.
My pppoe0 has an ipv6 address starting with 2a02:580:31b: but pfsense instead reads the local-link one.
My routing table contains the ipv6 prefix but it seems to be ignored.i do have ipv6 connectivity from shell but cant manage thru pfsense or doesnt get recognized properly.

Ok i guess ill give more info to see troubleshoot the problem. My setup is re0 is my local lan ethernet and re1 is my connection to my adsl modem.
I use PPPoE on my wan(re1) interface. From what i managed to check so far is that instead of checking pppoe0 interface for my ipv6 address it checks re1.
Maybe i understood wrong when i was selecting re1 as my wan interface? Should i have checked pppoe0? But its not created till i logging thru pppoe so it cant be.
Maybe my set up is not supported for ipv6? And my re1 should have access to ipv6? i.e. I turn my modem back again to a router, it gets an ipv6 address and re1 gets an ipv6 address and everything works?
