you filed it as a feature request, not a bug.. Its a BUG not a feature if dhcpv6 is running when your using dhcp-pd but you can not edit its config or even view what its handing out that is a bug not a feature ;)

Well, as pointed out before, using the same /64 on both the WAN and the LAN interface won't work, and since all you get is a /64, splitting out a sub-prefix will be problematic as well (IPv6 is really designed to use /64 as the maximum prefix size for LAN use; things like SLAAC will not work with anything longer). So, not sure what to tell you at this point.

Hi guys,

So can anyone give me some idea where I should change the gateway to wan_stf as ermal suggested earlier in the thread? I'm stumped trying to find it and it's killing me thinking that I could be one single setting away from working 6RD on 2.1.2!

It looks like I got it permanently fixed, my mistake was to boot up my PC "too early" when the firewall was not yet ready (I shut down the firewall and the PC when I don't need it). For some weird (or not weird) reason my PC didn't get any IPv6-address, it kept sending solicit messages according to the DHCP logs, but never sent a request message…
After rebooting my PC, according to the logs it sent a solicit message, after receiving the advertise from the firewall it sent a request and got a reply with an IPv6-address and now everything is working... (so I guess it was a layer 8 error...)

Thank you!

I installed the alpha from 17th of April just now. 6RD is still not working, but it does not seem exactly the same either. A few examples:

A promising log entry:
php: rc.bootup: ROUTING: setting IPv6 default route to 2a01:79d:3e85:a408::213.167.115.92

But:
wan_stf is gone from ifconfig, and no ipv6 config apart from fe80 (local link) addresses are seen.

The IPv6 address is gone from status | dashboard | wan.

These two last problems are probably related to 6rd failing on creation, I have posted this issue in https://forum.pfsense.org/index.php?topic=75707.0

OK, quick update. Previously, the LAN interface was not getting anything but the link-local IPv6 address, but after a reboot, it's now getting a /64. Machines on my LAN are also now getting addresses within that /64, so this issues seems to be resolved. Thanks again.

Bumping to see where I can resolve this issue. As a lark I install m0n0wall and setup IPv6 there. PD allocation worked, yet still no LAN traffic passing the local netgear modem.

But when I did enabled IPv6 on the LAN interface, the link-local always stayed in EUI64 format. So just trying to figure out what portion of pfSense code is changing the link-local addresses to fe80:1::1:1, and how to revert back to SLAAC-style addresses.

@adler187:

After changing the 'gif tunnel local address' to the IPV6 local address on the GIF and setting IPV6 to None on the interface, I got things working.

Yes, that is how it should be. :)

You are indeed wrong; this is perfectly normal for IPv6. Typically an IPv6-enabled host will have a SLAAC address (generated from the NIC's MAC), a temporary address (IPv6 privacy extensions), and possibly a DHCPv6-assigned address on each v6-enabled interface, plus link-local addresses. For privacy reasons, the temporary address is what will generally be used for outbound connections (which is what those websites will see); however, you should still be reachable at the other addresses for inbound connections.

Yes, thank you. That's where I went wrong. I see it now.

Can't really tell you what it means.  But, I can tell you how to clear it up.

Shutdown pfSense and power off the cable modem. Power on the CM and wait until it syncs. Boot up pfSense.

The errors will be gone.

Probably the DUID.

The problem seems to have been resolved in 2.1.1, as the tunnel now works without setting the default gateway. The manner in which the OPT-interface can have its IPs set has changed from 2.1 to 2.1.1

Thanks to everybody and apologies,

I am restarting all configuration from scratch (I did not finished yet, but I believe I am on the right way).

Anyway I think the many changes I operated stratified badly compromising somehow the final result with unreasonable results.

Should I get in trouble again I will provide more details.

Thanks again and regards
