18.7 Legacy Series / [resolved] ipv6 problems with 18.7
« on: August 09, 2018, 09:14:52 pm »
I recently upgraded to 18.7 from 18.1. Prior to 18.7 ipv6 (mostly, see below) worked fine but since the upgrade the dhcpv6 service crashes or stops shortly after boot and computers on the network don't get an address (though my laptop did get an ipv6 address one time apparently before the service stopped). Restarting the service doesn't work. I can't find any logs associated with the dhcpv6 service to get any information about what may be happening.
The second issue (and it maybe related) is a little more complicated. I have a VLAN associated with the same port as my LAN which I use for guest wifi. The Unifi AP tags the packets for the guestwifi with the VLAN id. It works great on ipv4 but with ipv6 something is leaking. My laptop which connects to my LAN wifi (not the guest) ends up getting 4 ipv6 addresses; two for the LAN network (which my laptop connects to over non guest wifi) but also 2 ipv6 addresses for the guest network even though it's not connected to the guest wifi.
Any ideas what is going on or what I can do to start debugging?
Thanks
