Supply the following if possible:

  • Device problem occurs on:

Linksys WRT3200ACM

  • Software versions of OpenWrt/LEDE release, packages, etc.

All versions were tested and report the same problem

  • Steps to reproduce

Flash any version of OpenWRT and watch the log for a message saying:

Thu Jan 1 00:37:11 1970 daemon.err odhcp6c[1573]: Failed to send DHCPV6 message to ff02::1:2 (Address not available)

I've searched all over but found no solution.

One thing that I noticed, I configured the device to use vlan 12 as WAN (in switch), but when I type swconfig dev switch0 show in the command-line the cpu wan and actual wan port have

Port 4:
mask: 0x0000: (4)
qmode: 3
pvid: 0
link: port:4 link:up speed:1000baseT full-duplex
Port 5:
mask: 0x0000: (5)
qmode: 3
pvid: 0
link: port:5 link:up speed:1000baseT full-duplex
Port 6:
mask: 0x0000: (6)
qmode: 3
pvid: 0
link: port:6 link:up speed:1000baseT full-duplex

As you can see the pvid is 0 Also, the WAN6 interface receives a global ip from the untagged interface, even when asked to be tagged as vlan 12.

PS: once, I got a error saying permission denied instead of address not available.
