hmmm, so there is nothing else going on on the network. Could you post the output of ip a and cat /etc/network/interfaces? Does ethtool <NIC> look different with the live disc? What kernel are you running on PVE and with the live disc?

Hey, so your home network is 192.168.4.0/24 with your router being 192.168.4.1, right? Usually post-up and post-down are part an interface configuration, so here those should be in the block for vmbr0. What does ifreload -avvv say? The ... state DOWN ... in both the physical NIC and the bridge...

I see, thanks for the clarification! Hmm, my best guess is that during the test something else was happening on the network or the TrueNAS server. Did you repeat the iperf3 PVE<>TrueNAS with some time in between? If yes, did the BW change, or was it ~6.5 pretty constantly?

ohh sorry, this one gateway 192.168.0.255, the gateway is a default route set (ip r)?

Hey, can you ping - the GW - other devices on 192.168.0.41/24 - 8.8.4.4 ? What is the output of ifreload -avvv?

is just adding the one you want to the whitelist, and blocking everything else not an option? Did you go through [1]? Should be pretty straight forward, having gone through the docs. [1] https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#chapter_mailfilter

Hey, blacklist is the one place you don't want it in if you want mails delivered :) Did you take a look at [1]? Do you have any specific questions about the rules system? [1] https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#chapter_mailfilter edit: ohh sorry, didn't read the title. If...

Hey, just so I understood this correctly, PVE <-> TrueNAS: 6.5Gbps PVE <-> something else on the same network: 9.36Gbps right? PVE, especially on the host itself, is just the linux networking stack. Do you have anything setup that would interact with the traffic? What is ethtool <NIC> saying?

Hey, not really. You could give dnsbl_threshold[1] a try, but with these checks postfix doesn't even accept the mail, there is nothing to put into quarantine so to say. There's also a SMTP whitelist[2], but for DNSBL you have to enter IPs. So a combination of tweaking the threshold and maybe...

Hey, what do you mean with loosing data? Some things to consider - the cluster needs its own network - backups target storage should not be the same as VM storage - if you use ceph, it should also have its own network. You really don't want high network load impacting your VMs IO performance...

Hey, no, not if they would end up being on the same disk. And even if you had more than one disk, I'd really recommend letting the installer setup booting from ZFS. So the best way to achieve that is to create backups of your VMs/CTs, then reinstall your PVE host with ZFS, then restore the...

As mentioned by my colleague in [1]: so no fixed date yet. [1] https://forum.proxmox.com/threads/proxmox-ve-9-0-beta-released.168619/

Hey, debian trixie has 3.10[1], which should include what you're looking for. We mostly just take the versions debian ships, and for bookworm that was 3.7[2]. Our PVE 9 beta[3] is trixie based, so either wait still stable, or try the beta. Alternatively just adding the trixie debian repos...

Well, just create a second one :) Maybe a Linux based one, might help rule out windows as the problem.

Hey, hmmm, could try setting the source address explicitly with -j SNAT, should look something like this: post-up iptables -t nat -A POSTROUTING -s '192.168.101.0/24' -o vmbr0 -j SNAT --to-source 192.168.31.222 post-down iptables -t nat -D POSTROUTING -s '192.168.101.0/24' -o vmbr0 -j...

Hey, auto vlan800 iface vlan800 inet static address xxx.xxx.xxx.xxx/24 mtu 9126 vlan-raw-device enp3s0f0 the vlan-raw-device should be the bridge, so vmbr0 instead of the interface directly. Did not look into this super close, I might have missed something else.

there is no difference between changing the IP or the subnet, both are part of the address, it doesn't matter which part of the address is changed.

Hey, I assume you mean that the PVE host uses DHCP instead of a statically configured IP, not setting up a DHCP server on the host. It is recommended to stick with a static IP for the PVE host, for standalone hosts changing the IP is somewhat straight forward, you basically have to update both...

Hey, what are you updating? Version 2.x of what, PBS? At the end of what did you find bash: /.cargo/env: No such file or directory?

Ok, exists:%{i}.spf.hc697-83.eu.iphmx.com sollte zu exists:23.90.105.144.spf.hc697-83.eu.iphmx.com werden, und per [1] passt das solange es einen A record zu der Domain gibt, allerdings scheint es keinen zu geben. Hier wird nur %{i} [2] verwendet, ich nehme an das ist so gewollt. Warum...
