The only error I see is under vmbr0 the line iface vmbr0 inet static should no longer be static but should now be manual iface vmbr0 inet manual. Not sure if that will impact vmbr0.10 though. Change that then ifrelaod -a and see if you can get a connection. Have you double-checked that your...

Can you copy your /etc/network/interfaces file here? After making the changes did you reload the Network ifreload -a in a few rare instances people have had to reboot the Proxmox node to get Network changes such as vlans to come up correctly.

I find it easier to think about a linux bridge (vmbr#) as a switch with unlimited ports. When you define an IP/Gateway at the proxmox host level (with or without vlan) this is like plugging the proxmox host into the switch and not the Guest (vm/LXC). So adding a second IP address in a different...

Maybe I am misunderstanding the problem, but you would not need to define/create the 2 other VM IP's in the Proxmox host /etc/network/interfaces file at all. Using your second example /etc/network/interfaces file option, You create/install the 2 VM's and use vmbr0 as the Bridge for the network...

vmbr0 is just the default Proxmox starts naming bridges with, but it holds no magic otherwise. The management IP could be assigned to vmbr1 or vmbr67 and any vlan from 2-4094. vmbr0.10 is tied to vmbr0 by standard naming nomenclature. Just as vmbr67.8 would be one way to define/create vlan8 on...

What version of VyOS? I have 1.3.2 running in my home lab, but not there at the moment. by memory I did not use bridges in VyOS though. I set up the Vlans directly on eth0 interface not a bridge. maybe I am missing something, but Why have separate vlans at all if you are just going to bridge...

@spirit What is the cli command verify these new default setting? Should we check from Proxmox host cli or vm? any general advice on the number of queues relative to the number of VM vcpus? 1 to 1 a good starting point?

to be clear you intend to connect the Proxmox node directly to the internet without a firewall? connecting to the internet is not the same for everyone. What type of internet service provider (ISP) do you have? Do have modem? Is there a modem and dhcp server connected to the layer 2 switch...

How you set up the proxmox host networks will depend on your network topology. Do you have vlans in use already? Will the proxmox host be behind a physical edge firewall and/or ISP router/firewall? Will the proxmox host have a Firewall/router VM/lxc guest and how would you like that to fit into...

Typically significantly easier to just use Linux Bridges and not do pass through as pfsense suggested.

Just to confirm, does the modem need the wan traffic Tagged100 or is this your design? not saying anything wrong with that design. What isp modem are you using, pfsense has issues with some. Have you restarted the modem and tried to allow pfsense to get a DHCP address, some won't respond to a...

So looks like things are setup appropriately from the 5G modem -> passthrough USB-> to OpenWRT->vmbr1->pfSense->vmbr2(lan) right now the pfSense lan (vmbr2) is not physically or virtually connected to anything else from what I can tell. 1.what Is the pfSense lan gateway address? 2. What is the...

Thank you. Lots of things going on here and still trying to conceptually unravel what you have connected to what and how. Answer 1 you say enp1s0 is connected to pfsense box? Confusing is this the pfsense vm or another separate pfsense box? You never answered specifically what box/device holds...

Couple things, the default Proxmox Linux bridge excludes the use of vlan1 tagged. Would need to change the line bridge-vids 2-4094 to bridge-vids 1-4094, but I don’t think that is neccessary. Vlan1 is untagged on switch port 8 meaning untagged traffic coming in from proxmox, pfSense or VM’s...

Let's try this again: 1. what is enp1s0 connected to? similar question, what is the 192.168.100.2 gateway connected to vmbr0? is this gateway the isp router/modem and does it do DHCP? 2. take screen shots of the network connections from the proxmox gui of OpenWRT vm and the pfSense VM. Trying to...

OPenWRT uses iface enx000ec6ca3c39 for wan then? What Linux bridges does OpenWRT use? for Wan and for Lan? Does or will anything else connect to OpenWRT besides pfsense?

No, sorry you misunderstood my suggestion. Recreate the vmbr1, but this time select enp6s0 as the Bridge Port within vmbr1 bridge. then try and use vmbr1 as the pfsense LAN again. next see if devices plugged into enp6s0 get a DHCP from pfsene or can ping the pfsense gateway. from the very first...

Something is wrong with the enp5s0 nic. It is not even listed with ip a. May be broken. Switch the bridge port on vmbr1 to enp6s0, and plug into that nic at least as a test. then I would suspect things work as expected with anything physically plugged in there. Are enp5s0 and enp6s0 from the...

What does ip a show? Have you tried switching vmbr1 to eno6s0?

So have you tried giving the proxmox2 node an IP/CIDR on vmbr1 using an IP from the pfsense lan subnet? Something like 192.168.100.2 since that is outside your pfsense lan DHCP pool. Leave the vmbr1 gateway unfilled for now, but eventually, you may want to switch that over from vmbr0 (current...
