Hello.
I've got TLWR-1043N with openwrt onboard. I have wlan0 and eth0.2
# brctl show
bridge name bridge id STP enabled interfaces
br-lan 8000.0023cd1c4012 no eth0.1
wlan0
There is aiccu and radvd running on the router. radvd sends
advertisements through br-lan. Wired hosts receive advertisments while
wirleless don't and it looks like it is the router which has problems
transmitting them. I say so because:
* arping to from the router to the wired hosts works, to wirelsess don't
* arping to wireless hosts from the wired once don't work
* after brctl stp br-lan 1 the wireless hosts don't see stp packets
* Only the router responds to ping ff02::1[*] from the wireless hosts.
The wired hosts start responding (to ff02::1) after pinging them
directly with their link-local address. They stop doing this (actually
they try as they receive requests) after ~75 seconds of inactivity.
tcpdump on the wired hosts shows that they receive echo requests
directed to ff02::1 for the first time they send multicast ND packets
which seem to be unable pass the router (bridge).
* Echo requests from the wired hosts to ff02::1 don't hit the wireless
ones.
Tcpdump on the wireless hosts show that no multicast or broadcast
packets hit them.
I don't use ebtables and iptables doesn't seem to contain any rules that
could affect the bridge code.
Has anyone seen this problem before? What is the cause?
[*] ff02::1 all hosts on a link multicast group.
