Hi Connect from where to where ? Most of the solutions you talked about are firewall "ready to use" ... So if your proxmox is connected on LAN, WAN or OPT card, the implicit rules are not the same ... And you're problem seems to be a filter port issue. Regards

Hello Wake on Lan needs a network card connected that in fact is powered. As the VM does not really exist, for simulating this, the VM shoud be powered but in a "low powered" mode to only respond on a WOL packet ... I'm not sure that this functionnality would be power efficient regarding the...

Can you try to change the network driver from E1000 to Virtio ?

The IP 192.168.1.104 comes from the DHCP ?

Proxmox firewall is not activated ? Can your others computers ping your Ubuntu ?

I see a PFsense that is a FW ... You talked about a Pihole that is a DNS-liar ... I don't think I understand everything Who is the DHCP server ?

you setup network thanks to the GUI in Ubuntu or in CLI ?

both your network cards are connected to vmbr0 ? not one on vmbr0 and one on vmbr1 ?

Not the network config of Proxmox, the network config of your VM please ...

So that's a network trouble ... What is the Proxmox network setup of your VM ?

As your ping does not seem to work, that is to say that you can't reach the IP ... The name resolution contacts an IP do ask it the Ip corresponding to a name. If you cannot reach outside IP, you can't make the queries so your name resolution can't work. In the previous screen, the default route...

Used this tip several times with Debian (Ubuntu is based on Debian). Works perfectly in Proxmox VMs Regards

HA begins with 3 hosts in most of the virtualization platforms (not only Proxmox). Proxmox with de replication process can nearly achieve the same with only 2 hosts. Nearly all is explained in this article (https://pve.proxmox.com/wiki/Cluster_Manager) But the quorum wants more than half the...

That is to say that you must have a dedicated network interface for cluster network ? A classical way to build Promox, in my opinion, is to connect SAN on a side, and on the other side 2 high speed nics (10 Gbs mini), each one of them connected to a high speed switch that runs with backup or...

You want quick explanations ?

Your question is : what is the pros and cons of network bond ?

My mistake ... I don' clearly understand. The firewall only knows what to do looking at IP or TCP Ports. You're right, as you have not IP yet you cannot use the 2 rules I propose. In DHCP, you can assign IP Address thanks to macaddress with lines in your DHCP like : host server1 {...

When you said that none can ping ... you tried to ping an IP address (ping 8.8.8.8) or a machine name (ping www.google.com) ? Regards

I think you can create a rule to allow DHCP ports for all the VMs Then another rule that blocks DHCP ports As the firewall inspects the rules sequentially, if the first rule match, the process stop and the second rule is not used Regards

As all is "virtualized", maybe you can add another virtual HD using a different controller (default or SCSI single) and test the copy speed ... Just to see if this is the VirtIO with this physiscal disks combination that is slow ... Maybe you test with a Linux VM and see other results ? Regards
