Nope.  ATT went native IPv6 a long while ago, so it's pure IPv6. no 6RD.

working great with https://github.com/aus/pfatt (with a minor mod to skip some pfSense specifics).

Now I can get all the info I need/want, and it all works.

Thanks for a great product! (running on an old protectli FW1).

Well, I'll be.... If I set up a static address on an interface, I get the ability to set all this up already.

Never mind.

Basically if we're using ISC DHCPD, where can I add statements to the dhcpd.conf that won't get wiped by the GUI making changes.

I'm coming back to OPNSense after a LONG break and was wondering if the DHCPD in current production can support doing DNS updates to a foreign (to OPNSense) DNS server (my server on a different network, using BIND 9.13.x) via an NSUPDATE type message, but using T-SIG keys?

Yep.  And it may make me rethink what I use for a firewall.  I may move to a Ubiquiti USG (I have Ubiquiti AP's anyway). 

I sent a tersely worded PM to Jim.  I'm *NOT* happy.  I also posted to the freebsd-net list about this.   

I'm actually on the 2.4-RC, and you are correct that it's mostly working, and I'm in that bug thread.

I'm also (somewhat) friendly with the netgate folk (they & I are in Austin, TX).

I'll poke at them.

I'm currently back to pfSense as they correctly support ATT Fiber's 6rd IPv6.   I really(!) prefer Opnsense, but *NEED* 6RD to work.

What's the current 6rd status in Opnsense 17.7?

Got ATT to swap me to a Arris NVG899 Gateway, and all works with pfSense.  OpnSense has issues with the 6rd setup.

Ok, game over:

I set up a HE.net tunnel, and it doesn't work either in DMZ+

Above is a smoking gun.

I get addresses delegated to the lan but they do *NOT* work.  My suspicion is that the 5268AC doesn't really pass *EVERYTHING* to the DMZ+ device.

ATT Support has been exactly *USELESS*

Anyone?

it was a hack that didn't work out.

Now what I have is:

ATTONT-> ONT Port on 5268AC
                 5268AC ETH1 -> WAN port on OpnSense
                              LAN port on OpnSense -> my LAN

The 5268AC is set in DMZ+ mode for the OPNSense MAC

The WAN port on OPNSense is set for SLAAC (for v6) and DHCP (for V4)

ping6 from within the FW works fine.

if I put a static V6 address on the LAN port, and have radvd running, my LAN devices get a IPV6 address, but no IPv6 connectivity.

What am I missing?

(here's the post I made to freebsd-net with more details):
I just moved into a brand new house, and it has ATT Fiber.  I have their
gateway (Pace/Arris 5268AC) in DMZ+ mode with an OPNsense (FreeBSD 11)
Firewall Router as the DMZ Host.

I can get IPv6 on the router / FW:

ATT uses 6RD:
6rd IPv6 Internet Connection Type    Value
Default Gateway    2602:300:c533:1510::1
6rd BR    12.83.49.81
6rd Prefix    2602:300::/28
6rd Delegated Prefix    2602:304:cfaf:f750::/60
6rd MTU    1472

How can I extend this to the LAN?

I currently have the LAN defined with an address out of subnet 1.

and if I have my Mac or FreeBSD box SLAAC, the IPv6 packets do not traverse to the
internet.

If I tcpdump the LAN interface, I see the packets enter, but nothing leaves.

Anyone have an idea on what I'm missing here?

(or is the Pace/Arris box getting in the way?

No go.  If I set WAN to SLAAC, remove the 2nd interface to the 5268AC, I can ping6 from the FW, but can NOT get IPv6 to work on the LAN.

see my post to freebsd-net@FreeBSD.org.

I've just moved into a nice new house with ATT Fiber.  ATT'S RG (Pace 5268AC) doesn't pass IPv6 through to the DMZ+ host (will be the firewall).  It *DOES* however allow IPV6 to other devices connected to it's own switch.

Should I be able to route IPv6 from another interface to my LAN and do Firewall stuff?  My suspicion is YES, but I'm not near it right now.

Basically the setup:
                                                    +--->WAN port on OPNSENSE (IPv4/DMZ+)----+
ATTONT->ONT PORT on 5268AC ---|                                                                     |----> LAN port on OPNSENSE
                                                    +--->OPT1 port on OPNSENSE (IPv6/DHCPv4) .+ 

Would this allow me to have dual stacked hosts on the LAN ?
