Ping issue

[hardwarenerd]

Hey, just wondering if anyone else has had this problem. I'm running everything that I'm working with behind a dedicated firewall running Opnsense to an unmanaged switch. I have my main pc and a laptop that runs Proxmox on the same switch. My pc can ping Proxmox and access the web GUI, but Proxmox can't ping anything. And I'm running Proxmox on bare metal. I've checked the gateway and made a rule in Opnsense to allow Proxmox, but still having the issue.

Hi,
Proxmox behavior depends on what you configured.
You could start from checking whether the interface and bridge actually have the correct IP/gateway.
Test ping the gateway (if not tested), if there no ping check what is default outgoing interface for ping.
Check the

ip route

and make sure the default route points to your OPNsense LAN gateway.
Check the PVE firewall rules.
