Outside access from Proxmox host

[d5ovetov]

Currently I have a OPNSense VM running on Proxmox. I can access the internet and Proxmox, but I can't access the internet from the Proxmox host, or any VMs or containers. It can't even ping gateway. All was configurated before me and I can't change it right now.

The Proxmox host network setup:



The biggest issue is if I change anything in vmbr0.10 all LAN would crash (I had already tried it during work day in my shame)


I need to understand what can I do to allow Proxmox host reaches at least LAN and Vlan1 (subnet 10.0.0.0/16).


P.S.: machines from Vlan1 and Management can reach each others.

To me that looks like the opnsense VM (don't know this one, using pfsense) is connected to the wrong networks.
Can you share the VM network configuration of that VM?

Is this the only NIC?
How is that supposed to work???
Do you use VLANs within the VM?

This isn't only NIC. VM has more. All connect to vmbr0 with different tags (vlans)

Please share the complete nic setup.

Please share the complete nic setup.

One network device connects to first WAN;
One network device connects to second WAN;
One is on screenshot;
One network device connects to second VLAN (Vlan1).

Trust is set up between vlans (VMs can reach each other).

Do you have any ideas or you're just interested how is set up?

I am trying to figure out what you are doing and where the problem might be.
Without information => no help.

You are describing an issue asking for help but seem unwilling to share information. Even your last answer is not helpful because I have still no idea how your setup looks like in detail.

I have such a setup running since years and it runs fine. So there is a detail that prevents you from doing what you want. With highlevel information it is hard to impossible to help you. Why would I want to replicate a config which has issues? Wasting time? Sure not. Good luck. I'm done.
