Hey,

I have a cloud server, a vSwitch & a dedicated server at Hetzner.

These are connected as follows:

I can ping 10.0.0.2 from the Proxmox host. From the guest machines too.

The guest machines should use the PfSense (cloud server) as a gateway to the Internet and for routing.

I can ping them. But don't use it as a gateway.

Anyone have any idea what I need to put there?
I haven't been able to get there for 2 weeks.

Thanks!

Sorry, I didn't pick up on the fact that pfsense is running outside of Proxmox.

So your VM's have an ip setup like

address 10.0.1.5
subnet 255.255.254.0
gateway 10.0.0.2

Is that correct?

no the Proxmox has an own subnet via vswitch and should be routed by Hetzner.
10.0.1.5
255.255.255.0
10.0.1.1

But your VM's can reach the internet? What does a 'traceroute' on one of the VM's tell you about the network route?

I meant from your proxmox host (10.0.1.2) to 10.0.0.2

what does this mean? please be more specific and provide some examples of what works and what doesn't - remember we don't know how you have set things up...

You have said you can reach the proxmox host, on Hertzner hosting, so we assume that networking on the left side of your diagram is working, but now the traceroute results you provided suggests it isn't??? And if you can't reach your host, how did you create any VM's ??
