Hi guys, I would like to allow access to SSH from only one IP address (100.100.100.100 for example). So, I set up in Proxmox firewall these rules: 0: Direction: in Action: ACCEPT Enable: yes Source: 100.100.100.100 Protocol: TCP Destination port: 22 1: Direction: in Action: DROP...

The switch config was shown above, already. It is configured as an eth trunk, with mode LACP - no loop there on the bond side. Nope, the current network configuration is not posted here. I told you, already, I altered it after the discussion. Also, once again: auto enp3s0 iface enp3s0 inet...

First, I will ignore the arrogant and untrue shit in your first statement, alright? Second, I still thank you for your effort, but you are just plain wrong about the issue here: I have the two interfaces (one NIC for management and two NIC for bonding) working and everything is/both are fine...

Unfortunately, I have now this problem: https://forum.proxmox.com/threads/proxmox-6-and-ryzen-3700x-x570.58359/ I found out the connectivity problems I had, also my issue with the bonding seem to be the result of using a bridge (vmbr0). When I removed it and put the IP configuration directly...

Btw, it is now nearly 24 hours with only one disconnect. So, my problem was the bridge interface definitively. My problem stays then: How do I get all the VMs to talk with the outside world, if a vmbr0 is not possible? Or also interesting: What is causing the problems on vmbr0? Is that a...

Alright, I checked now everything: syslog, dmesg, several tcpdump files, ... and I really found nothing. I am lost here. But I did something just for testing purposes and I am having a session open for over two hours without a connection loss. I changed auto enp3s0 iface enp3s0 inet manual...

Anyone having experience with Ryzen 3000 or an idea how to troubleshoot this? Alone today I lost remote access (or got "connection refused") five to ten times without even doing anything. Firewall is turned off, fail2ban is not installed.

Alright, I changed it up like this: auto lo iface lo inet loopback iface enp3s0 inet manual auto enp4s0 iface enp4s0 inet manual bond-master bond1 auto eno1 iface eno1 inet manual bond-master bond1 auto bond1 iface bond1 inet manual bond-slaves eno1 enp4s0 bond-miimon 100...

Hi guys, I am new to Proxmox as you can see on my other post and I have done a fresh/vanilla installation. The server has a 3700X on a Gigabyte X570 mainboard and 32 GB RAM. I realised, that I am having a lot of connectivity problems, meaning often I cannot connect to the box without any...

Thanks, but there is a misunderstanding. There a three NIC. One NIC (enp3s0) for the management, the other two NIC (en0, enp4s0) form the bonding and shall be uplink for the VMs, ... etc. So, vmbr0 is management with enp3s0 and bond1 the uplink with en0, enp4s0. LACP is mode 4 under bonding...

Alright, the server was placed now in the data center behind a Huawei switch. The switch's configuration is this: interface Eth-Trunk10 description #### Server #### port link-type trunk port trunk allow-pass vlan 167 mode lacp load-balance src-dst-mac Bond0 status: root@rakete:~# cat...

Alright, I will use Debian's or Proxmox's firewall then and just forbid access to the WebUI on the host. Does this affect the guests/VMs, too? Are you saying I can spare one of my precious six IP addresses? :D No, seriously, how do the guests/VMs communicate with the outside world, if the...

Well, I thought about using Linux bonding with this configuration: I hope, this configuration is without errors.

Alright, I have two more questions, but I did not want to open up another post just for that. As mentioned earlier, I am using three NICs on the machine - one for internal connection, meaning the Proxmox interface and two for LACP bonding, meaning the internet access. 1. How can I restrict the...

So, a LACP bond will not give load-balancing and double the speed, just a fail-safety. That is nice, but still what a pity. Is there another way to use those two NIC together to utilise double the speed? Nope, I have tree NIC: Two for the public IP (LACP bond) and one for the private IP...

Hi guys, I am building up my server with two NIC (Intel Gigabit adapter) this week and will use the newest Proxmox version for installation. Eventually, the server will be positioned in a data center behind a Cisco or Huawei switch with two 1 Gb ports, which I will have configuration access to...

Alright, I will do it with one VM for each gaming instance. To be honest, there will be nothing critical on those VMs, at all, and also, the content is getting backupped daily/weekly to another server in a different location just to be sure. So, you would propose, rather to use two 500 GB NVMes...

Hi guys, I am absolutely new to Proxmox and also have never installed/configured a virtualisation server for hosting several VMs. So, I heard and thought, Proxmox seems a good idea for that, especially, as I like Debian a lot. The system will be: Ryzen 7 3700X, 32 GB RAM, Gigabyte Mainboard, 1...
