Good to hear.

Is yours configured as a bridge anywhere? My apu2 (x86) is not.

I can reconfigure a wndr3800 "out of the box" with both head and
stable and try that in a night or two on the network where the
arm is working. (production network can't fiddle)

As per the bug report, I see no responses to my ip6 queries.

Had 24 days of uptime...


root at office:~# ifstatus wan6
	"up": false,
	"pending": true,
	"available": true,
	"autostart": true,
	"dynamic": false,
	"proto": "dhcpv6",
	"device": "eth0",
	"data": {

I should see at least *some* ipv6 traffic here?

root at office:~# tcpdump -i eth0 ip6
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 262144 bytes
19:41:55.339916 IP6 fe80::20d:b9ff:fe43:a06c.546 > ff02::1:2.547: dhcp6
every x seconds...

... that's it.

ip6tables -F as well as -P whatever ACCEPT

Tried both reqprefix 56 and 60.

config interface 'wan6'                                                         
        option ifname 'eth0'                   
        option proto 'dhcpv6'                  
        option reqprefix '56'                                                   
        option dns '2001:558:feed::1 2001:558:feed::2'


while I'm here, have you had any success in getting a relay to work?
