ipv6

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...

Hello guys I've been facing problems since always related with configuring all LXC's and VM's with ipv4 + ipv6 in OVH. There are 5+ posts in this forum related with that, but not even a completely working tutorial so the community users can finally configure they're machines in the correct way...

Since my ISP started deploying IPv6 to all clients, i'm facing problems with my proxmox server... If i leave the IPv6 configure on my router, proxmox will not start the services after a reboot... IS ther any specific configuration to be made in order to make proxmox IPv6 friendly?

Hello, I have a problem on several VMs running with Windows (Windows Server 2022 or Windows 10) regarding IPv6 connectivity in my Proxmox VE 7.3.4. Indeed, on each VM I have a network device in model VirtIO (paravirtualized). The guest agent (virtio-win-0.1.173-2) is installed on Windows...

Hello, I set up a cluster in dual stack IPV4/IPV6. I would no longer like to use IPV4 on the cluster so I would like Corosync to be only in IPV6. In corosync i have : node { name: test1 nodeid: 1 quorum_votes: 1 ring0_addr: XX.XX.XX.XX <= IPv4 ring1_addr...

Im currently running proxmox 7.3. When provisioning Ubuntu VMs (20.04/22.04) the vms auto assign IPv6 addresses in addition to the ones defined in cloudinit. This makes it a bit difficult to manage firewall rules and such. Is there a way to adjust the cloudinit image proxmox generates to include...

Hi, I have a Proxmox host running a dedicated server from OVH. They provide both a single public IPv4 address, and a IPv6/64 block. I'd like to route all the IPv4 traffic from containers on my host through NAT, but set a proper public IPv6 for direct access. I've succeeded in getting the IPv4...

https://pve.proxmox.com/wiki/Network_Configuration#sysadmin_network_masquerading I'm currently using this setup because my hosting provider gives me a single IPv4 address, so I have to set up masquerading. I'm setting up a new Proxmox host, and I'm considering adding IPv6 configuration from...

Hallo liebe Proxmox-Community, ich versuche gerade herauszufinden wieso die neuen Agents von CheckMK 2.1 auf meinen VMs nicht funktionieren. Ich glaube ich habe mich dem Kern des Problems genähert: Laut nmap ist Port 8000 bei Verwendung von IPv6 filtered, bei IPv4 aber open. Offensichtlich...

I don't know when this issue started, but I have IPv6 disabled via grub by using "ipv6.disable=1" on GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub. My syslog is being flooded with the following messages: Nov 19 10:53:24 pve pve-firewall[1053]: status update error: iptables_restore_cmdlist...
