ipv6

I have an issue with two Proxmox hosts which are misbehaving when establishing connections with pretty much anything. My own applications, apt, curl, ping, you name it. Both on the host and within LXC containers, things keep attempting to connect via IPv6, even though no IPv6 service is...

I'm trying to set up a server with routed networking. My host has given me: Public IPv4 IPs: 170.1.2.88/29 IPv4 Gateway IP: 170.1.2.89 Public IPv6 IPs: 2600:1234:1234:1234::/64 IPv6 Gateway 2600:1234:1234:1234::1 Here is my /etc/network/interfaces on the Proxmox host: auto lo iface lo inet...

Why Do It? With the increasing pressure to transition to IPv6 due to the rising costs of acquiring IPv4 addresses, this guide aims to provide a collaborative comprehensive overview of setting up Proxmox vms with only IPv6 addresses (single stack) while still allowing access to and from...

Hello I am moving VPS's from Virtualizor to Proxmox. On Virutalizor, IPv6 was working perfectly with IPV6. Unfortunately with Proxmox IPv6 is not working on the VPS's The router in the DC is a Mikrotik with IP 2c0f:eb89:1::1/64 assigned to the interface that connects to Proxmox. VPS's have...

Hello :) I am running into a weird issue where on a vlan a vm would not be able to find the gateway set (also a VM) using neighbor discovery. After some debugging I found that on the cluster node where the gateway was running, the neighbor solicitation packets from the client were visible on...

Moin! Seit 2 Tagen versuche ich Proxmox mit IPv6 an den Start zu bringen, aber iwie bin ich anscheinend zu blöd. Der Dedi steht bei Hetzner und ich bin brav nach Hetzner Anleitung vorgegangen (Routed Setup)...

Good day, I have new set of clusters to be deployed in environments where I do have needs for SDN (vxlan-evpn) and loopback routes for CEPH while preparing for IPv6 only networks. Though I did got it going at one stage (IPv4 only), there are still missing pieces/processes that I'm stumbling on...

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...
