ipv6

IPv6AcceptRA seems to be auto-set to False when setting LXC containers to DHCP on network settings for IPv6. Is there a setting I can adjust to change this to True?

I have Proxmox setup with a single network card and software bridge. The physical network the host is connected to provides IPv4 via DHCP and IPv6 via SLAAC. I can create VMs with VirtIO NICs and the firewall option disabled, install Linux and everything works (the VM gets IPv4 and IPv6...

My ISP has assigned me a block of ipv6: 2001:19c0:1::1c00/120 I'm currently on Proxmox 7.4. After setting up a new Ubuntu 22 LXC, I've added network settings like so: Static IP: 2001:19c0:1::1c03/120 Gateway: 2001:19c0:1::1c01 I've also tried updating the bridge on the node to include an...

Hallo zusammen, kurz vorab, habt bitte ein wenig Nachsicht mit mir und Netzwerk :) Ich habe einen Dedicated Server bei Hetzner und möchte das ganze IPv6 Subnetz auf meine pfSense routen, damit ich das dann entsprechend an VMs weiterverteilen kann. Ich nutze das Routed-Setup und habe es auch...

A very newbie question: I've got a purely v4 Proxmox cluster, and want to migrate it (the internal addressing used for corosync) to IPv6 as an end goal. Would it be possible to add a node with just a v6 address, and remove one v4 node, and so on? Or can this be done with dual stack addressing...

Hello all, I am trying to set up my Proxmox PVE HOST to use DHCP to optain both an IPv4 and an IPv6 address for its Network interface. I would then manage the actual Addresses via static leases on my DHCP server. As the Guest VMs would have DHCP active and therefor pull IPs within the network...

Good afternoon! I am facing a challenge with a cluster hosted on OVH consisting of 5 servers, each with a public IP. The cluster is working fine with IPv6, but I have identified some vulnerabilities, such as public communication between servers, the absence of a private network, and direct...

Hi, currently one of my vlan is having IPv6 /48. I am currently assigning VM a /64 subnet and set that subnet to the IPset field. But when I add another IP outside that /64 (but within the same /48) to the guest os. It's still able to use that and I could ssh into the VM. Is it possible to fix...

Hello, we want to setup Simple SDN zones with IPv6 but can't find any documentation about how to configure SLAAC or DHCPv6 for a Simple SDN zone in the WebUI. Goal: Netcup-VPS with two public static IPv4 addresses and two public static IPv6/64 prefixes -> Headscale VPN -> Proxmox VE node ->...

Hi, i currently have some issues with ipv6. My plan is to create a setup like this: "proxmox <-> opnsense <-> vms". I'v allready successfully setup ipv4 with nat and all stuff, which works fine, but i would also like to use ipv6. With my current setup i can reach opnsense with it's ipv6 from...

I have a connection via tunnelbroker.net and tried to get it running on PVE 7.1-7 and had no success. I then loaded 8.0-2 on a small machine, and still no success. Went to he.net support, they tried it and it appears to connect, the tunnel does come up, verified by support at he.net and by...

I have tried everything - even reloaded it completely. I cannot get port to pull an IPv6 address from my pfSense Router. My ISP provides me with a /64 IPv6 block and I am using prefix 0 (all of my other systems will pull an IPv6 address). COMCAST uses DHCPv6 (with Track Interface of the WAN)...

Hello! I'm quite aware that there may be a few threads that detail similar issues like the ones I am facing, however this seems to be slightly special, especially with OVH's strange networking. The following setup is given: Proxmox VE 8 Host on latest Version with all Updates installed. Said...

Hi, I'm running Proxmox 8.0.4 on a two node cluster plus a qdevice (RPi). Works well. My ISP recently enabled ipv6 with a dynamic /56 prefix which also works well. The wan gw acquires the prefix from ISP using WIDE-DHCPv6, and uses dnsmasq as DHCPv4 server as well as SLAAC for ipv6. Dual-stack...

Hi, I am installing Flatcar in a Proxmox VM. I have already several VMs working under the `vmbr0` bridge. I disabled the Firewall while defining the VM in Proxmox. Everything goes fine during the install from the Flatcar Production ISO image. But when I `ip a` , only IPV6 is available under the...

Hello, Is it possible to configure guests to have entire IPv6 without packet lost like this? I've GAME-1 with /64 and I'd like to have /128 on guests. I tried with NDP, etc. and it works very randomly. More details about configuration: https://github.com/DanielAdolfsson/ndppd/issues/81

Hi! I have run into some bugs after configuring static IPv6 address and gateway on LXC containers in proxmox. Some details about my network and the proxmox node, My WAN connection uses 1492 MTU (PPPoE). I use a IPv6 tunnel to get IPv6 connectivity. The MTU on this tunnel is 1472. I am...

Hi there, This is a bit of an edge case, though being so short on time it's taking me a while to understand the inner workings of IPv6. There's a reason they say "throw out your understanding of v4 as it has no bearing with v6", holy moly are they right! It's great but needs to be understood...

I am using Proxmox with several VLANs for VMs with an ISP that hands out dynamic IPv6 prefixes. Thus, my router gives router advertisements for different VLANs with their respective prefix. The VLANs are defined on the Proxmox host, where only one VLAN has an IPv4 assigned. So, I can connect...

I am seeing similar slow startup of LXc containers to those reported in this thread and elsewhere, However unlike that report I'm not using docker. I have a pretty "vanilla" installation of Proxmox 7.4.1, except for the fact that the bulk storage is on a BTRFS mirror. This machine currently...
