I'm guessing the promiscuous modes plays its part in this field.
You
can try setting the interface to promisc mode manually using 'ip l set
$dev promisc on' and see whether that helps without starting tcpdump.
Also check sysctl -a | grep 'ipv6.*forward'.
Thank you for your answer. IIRC forwarding is only required for routing.
I use bridge mode.
You are right - it's working with promiscious mode enabled.
Without:
2a01:198:200:8350:98ec:1708:c82e:a4fb dev br-lan INCOMPLETE
With:
2a01:198:200:8350:98ec:1708:c82e:a4fb dev br-lan lladdr
52:54:00:8e:b9:eb REACHABLE
Is it really required to be enabled all the time to make it work?
Cheers,
Stefan
