Hello,
I have some strange behaviours with IPv6 on my Proxmox server
First of all, my ISP is providing native IPv6 connectivity and usually I have no problems with it.
The story is a bit different with Proxmox / Debian
Essentially my Proxmox host has somehow got an IPv6 address but it is "unable" to use it
The vmbr0 has two IPv6 addresses, one auto assigned (fe80:..) and another one that looks like a valid address.
Despite this it has no connectivity, for example
That said, the behaviour of the virtual machines deployed on the host is different
- Ubuntu installations have no problems, they have IPv6 address and connectivity "out of the box"
- CenOS7 (1511) have no IPv6 address after they are fresh installed, but after a yum update and reboot it works well as ubuntu
- Debian 8 virtual machines are not getting any IPv6 address and there is no way to obtain one. Also updating packages is painful because for some reasons apt-get is contacting the servers on IPv6 address and is waiting forever for the answer.
I can not find anything in the debian documentation or googling around, the only important parameter seems to be the auto or dhcp parameter on the line
in /etc/network/interfaces
Of course no one of them makes any difference.
Btw in Ubuntu is "auto" and it works perfectly
Did I miss something?
