@babine was this set-up at one point stable and functioning ? Was the MTU validated to be supported across all parts and paths ?

This thread to document what happened and how this was fixed, just in case this can help someone. Running pve-manager/8.4.1/2a5fa54a8503f96d (running kernel: 6.11.11-2-pve) in a single host set-up for a lab environment. The system typically is stable, until it is not. After a few 'hangs' this...

I'll have to check myself then, i don't remember doing this explicitly. Well, guilty. The system hung again this morning. I've now switched back to the 6.8 kernel, assuming the version will increase automatically over time.

well, then, you just answered

Hey Thomas My impression is the freezes happen every three weeks. I'm setting up grafana and other tools to get a better view. I'll update this thread after. Best JL

@t.lamprecht this is unlikely to be related but I've never seen this before cd /var/log/audit ls -l total 2771 -rw-r----- 1 root adm 222805 May 25 02:09 audit.log -r--r----- 1 root adm 8388822 May 25 02:08 audit.log.1 -r--r----- 1 root adm 8388688 May 25 01:46 audit.log.2 -r--r----- 1 root adm...

Thanks. I rather stick with something that 'just works' It is a really annoyance with Proxmox these freezes. These do reappear over time, just enough to 'almost forget' about them. To be honest they are a cause for paranoia. I've considered switching to another HV because of these. Since at no...

to my understanding this issue on topic of the thread only happens on single-node Proxmox VE, is that also the experience with others or was this a conclusion since rebuked ?

Similar unexplained freezes since a few weeks, before the system was running well without any issue, very cumbersome PVE 8.x with ZFS Linux pve 6.11.11-1-pve #1 SMP PREEMPT_DYNAMIC PMX 6.11.11-1 (2025-03-16T18:52Z) x86_64 GNU/Linux

this is an interesting remark I can maybe adde something to this because, after enabling SDN, the VM booted with a DHCP IP and were able to reach the internet then the IPAM IP was manually set and the VM rebooted, this resulted in the form mentioned error about thekelleys.dnsmasq i don't...

@cheiss @shanreich In the meantime I got SDN working, this does offer an interesting feature set what is unclear to me is if i can also use SNAT to translate traffic from the internet:port to a localIP:port using SDN EDIT: yes, SNAT + DNAT working fine

thanks, tried that, doesn't help

thanks for the follow @shanreich The documented example provably does not work, as others also reported in these forums. for example: ping -I exitnet 1.1.1.1 should masquerade the traffic and show echo-reply, it does not, this also shows the same when using tshark -i vmbr0 icmp 1...

thanks for the follow up. The for mentioned is illustrative to the minimum documentatin provided by Proxmox, which does not work for NAT/Masquerading for traffic to internet from any VM. Not matter what was tried of configuration. To my knowledge this should be adequate. auto vmbr0 iface...

Thanks for the elaborate reply. I'm still hurt with not being able to get IP masquerading to work with proxmox, regardless of anything I've tried. The documentation mentions this should work with an adaptation such as below, yet this provably doesn't work. Traffic exits without being natted...

To my shame and dismay I must post to ask for feedback on this. I'm not the greatest documentation reader but I think I covered most if not all of it regarding. To have the Proxmox firewall(s) working well is not proving 'easy' Not even with a simple set-up. To keep things manageable I started...

The procedure worked yet the validation is stuck in 'pending' Which is actually the result from the order URL also. Setting up webserver Triggering validation Sleeping for 5 seconds Status is still 'pending', trying again in 10 seconds Status is still 'pending', trying again in 10 seconds Status...

You're not providing much useful information and not seem apt at doing so. Hence my remark, Proxmox is an enterprise-grade open-source product. The WebGUI is to my knowledge the pveproxy process if this process is not running on the IP you expect it to run, no connectivity is the outcome. If...

@rodrigojds you seem to be way out of your depth here, why are you running proxmox ? why not try something more consumer oriented ?
