IPv4 AND IPv6 on Online Dedi w/ Proxmox

After beating my head repeatedly on the same rock, I am reaching out for help. I have an Online.net dedi (recent special, of course). It's running Proxmox and I have some failover IPv4s. IPv4 is working just fine with the VM I've set up on it so, no problems there.
Using instructions I've seen here and elsewhere, IPv6 is working on the host node. However, I have tried everything to get IPv6 working on the VM (KVM instance) and, I can't get it to ping out. I was wondering if anyone has been successful doing this (using both IPv4 and IPv6). Every tutorial/solution I have seen seems to be for IPv6-only configurations.
Thanks in advance for any help offered.

Not sure how IPv6 works with online.net but have you tried putting this in /etc/sysctl.conf
net.ipv6.conf.all.forwarding=1
No success adding IP with
ip
?Did you configure a bridge on your host node?
Well, here's what I did (on the KVM instance -- X's just to mask the IP)
when I ping the interface, I see that it's configured:
However, when I try pinging outside, I get nothing.
I did. However, after doing so, it seems like my IPv6 setup on the host would cease to work.
Do you mean in addition to the one created via the Proxmox install? No, I didn't. Perhaps I am just spoiled by OVH. Getting IPv6 working there is a breeze.
Please pates your /etc/network/interfaces, and perhaps we can help you.
Interesting.
Have you tried https://forum.online.net/index.php?/topic/4729-howto-ipv6-using-dhclient-for-ubuntu/#entry30969 ?
Works fine after adding my DUID.
Thanks but, is this a setup for the host node or the VM? I have it working on the host node but not inside a VM.
Yep, just add
net.ipv6.conf.vmbr0.accept_ra = 2
to /etc/sysctl.conf on host node and reload withsysctl -p
Note that I use different ipv6 subnets on my VM and Proxmox and the VM is bridged to vmbr0
I'll give it a shot. Thanks again.
@ALinuxNinja just wanted to say thanks. I finally got it working (after I realized that I needed to create /64 subnets to use in my virtual machines).
No problem, glad i could help
