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:
root@home-fw:~ # ping6 ipv6.google.com

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?
