Proxmox VE host: No internet and no access to local pfSense network

Hi everyone!

I have been searching around for answers and could not find a working solution. I am running Proxmox on a physical server, connected to the ISP router (192.168.1.X). Inside Proxmox, I am running a pfSense firewall and router (10.0.0.X).

The server has two NICs:
  • 1 x 4 port (enp1s0f0, enp1s0f1, enp1s0f2, enp1s0f3)
  • 1 x 2 port (eno1, eno2)

Network setup:
  • enp1s0f0 (vmbr1, pfSense WAN, cable directly from ISP router to server)
  • enp1s0f1 (vmbr2, pfSense LAN, cable from server to switch)
  • eno2 (vmbr4, cable from switch to server [to access Proxmox on the 10.0.0.X network])

  • Server gets the IP 192.168.1.X
  • pfSense gets the IP 192.168.1.X
  • Switch gets IP 10.0.0.X
  • Everything connected to the switch gets IP 10.0.0.X

Now, the problems:
  • The server cannot ping external nor internal IP addresses
  • The server has no internet access

Any suggestions on how to fix this one? Thank you very much guys
Networking for devices in the LAN through the pfSense FW works and only the Proxmox VE server is having issues?

Might be due do some routing issues in this setup.
Can you post the output of the following commands?
ip a
ip r
