I have a tiny lenovo m900 which i added a second ethernet port to and i’m trying to set it up as a proxmox server with OPNsesne. I’ve got the OPNsense VM setup with the two ethernet ports bridged to it. Everything is working fine on the network except my proxmox server doesnt have an internet connection. How can i set it up so that one of the ports acts as my LAN default gateway and also functions as the management port for proxmox. I’m guessing that’s what is causing this issue.
I’m a little confused. I think that’s exactly how I have it set up currently. The problem is that proxmox doesn’t get an internet connection. I’m unable to ping out or resolve dns from proxmox. The rest of the network is getting internet though. I reserved a static ip in OPNsense for proxmox. Could that be causing a problem?
It really depends on how you have your /etc/network/interfaces set up. For one of your bridges, proxmox needs to have an IP. If you want proxmox’s traffic to go through OPNsense, it should have an IP on the LAN bridge. You have to make sure the interfaces file explicitly sets a static IP or explicitly says it will get its IP via DHCP.
Since you set a static IP on OPNsense for Proxmox, you will need to manually set it to use DHCP on the LAN bridge. In my experience, this does not work because Proxmox will fail to get an IP via DHCP if OPNsense is not up yet. I highly recommend you set a static IP in the interfaces file.
