Hello everyone!
I'm not proficient in networking, and after two days of testing, I decided to ask here if what I'm doing is correct or not.
Let's start from the beginning: I just bought a Kimsufi server from OVH. A very good deal. Like every Kimsufi server, you cannot have more than one public IP. But for what I planned to do, it's enough. I installed Proxmox 8 on it, created a VM with OPNsense, and created two bridges like this:
Under the red lines, for the vmbr0 bridge, we configured the IPv4 and gateway with the same values as my server interface, retrieved from the OVH dashboard:
As you can imagine, this is my WAN. For the LAN, I created another bridge without a NIC. Here is a diagram of what I have in mind:
Right now, I'm stuck at the first step. OPNsense seems unable to reach the router. If I try to ping it, I get no response.
So I have two questions at the moment:

So I have two questions at the moment:
- Is the architecture I planned actually valid?
- Why does bridging the NIC and attaching it to a VM not expose it to the internet?
