[PVE-User] IPv6 problems after upgrade

[Holger Hampel | RA Consulting]

Hello,

after update to newest version of pve-no-subscription we have strange IPv6 behaviour:

- host machine works
- openVZ container works
- KVM machines: ping from host to link local addresses works
- KVM machines: only one can ping / be pinged from host machine but not outside

Is some else using IPv6 with this version? Good/bad experience? Configuration hints?

Here some information:

# grep v6 /etc/sysctl.conf
net.ipv6.conf.all.forwarding = 1
net.ipv6.conf.default.forwarding = 1
net.ipv6.conf.all.proxy_ndp = 1        ### but not set on any interface after boot
net.ipv6.conf.default.autoconf = 0
net.ipv6.conf.all.autoconf = 0

# pveversion 
pve-manager/3.2-2/82599a65 (running kernel: 2.6.32-28-pve)


Regards

Holger Hampel
