    [SOLVED] IPv6 via Tunnelbroker

    VE 8.0.4 how to enable IPv6 on Host port?

    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)...

    OVH: Setup with pfSense at OVH

    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...

    Managing ipv6 prefix on Proxmox cluster

    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...

    IPv4 not available in newly created VM

    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...

    OVH & IPv6 only

    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

    (LIR IPv6 /32 into 2x Routers) Desire: /48-per-Type, Routing to /64-per-VM & /128-per-Domain?

    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...

    IPv6 woes with dynamic prefixes and SLAAC

    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...

    (Another case of) Slow container startup

    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...

    Cloudinit disable dhcp6 and accept-ra

    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...

    NAT + IPv6 for containers on OVH Host with 1 Public IPv4 + IPv6/64

    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...
