      Hi,

      I'm running pfsense in a vm on Proxmox on a Miniforum ms-01.

      WAN is connected to i266-V intel Nic with DHCP and bridge mode from ISP router on 192.168.0.0/24 IP/subnet.

      LAN is i226-lm to unmanaged switch / Dumb AP / ethernet to computer on 192.168.1.0/24 IP/subnet.

      ISP modem is giving DHCP address to Proxmox / Pfsense no problem.

      However, LAN will not provide DHCP to LAN devices, static assigned IP works fine though. Nor can I access internet, ping sites, etc.(I read on another post that vPRO can block DHCP, unsure if this is true)

      Any help would be greatly appreciated.

        Did you pass-through the NIC to the pfSense VM?

          @viragomann Correct. Both NICs are passed through. I am able to set a static IP and load all local services (pfsense, Proxmox, Plex, etc) and pfsense has internet.

            @penne said in pfsense on proxmox - no DHCP - no internet:

            Both NICs are passed through.

            So I'm wondering, how Proxmox gets an IP from the ISP router. Or did I understood wrong?

            I'm not sure if the NIC is supported properly in pfSense. You could remove the pass-through and configure Bridges in Proxmox instead. So Debian would to the hardware management.

              @viragomann Sorry I misunderstood you and should have clarified in my original post. Both are setup as bridge connections. WAN is setup as a bridge to my ISP router and uses DHCP while my LAN has a set range of 192.168.1.0/24 and a gateway of 192.168.1.1.

                So pfSense just sees the virtual NIC. Do you use the virtio type? This should work well.

                WAN is setup as a bridge to my ISP router and uses DHCP

                So on the WAN bridge Proxmos has no IP set?

                while my LAN has a set range of 192.168.1.0/24 and a gateway of 192.168.1.1.

                Are you talking about the Proxmox bridge?
                192.168.1.0/24 is a network address. If you want to give Proxmox an IP on the LAN you have to state a usable one.

                And the gateway is pfSense?

                And you have also no IP / network set on a member interface in Proxmox?

                  Here are some screen shots I should have put in my original post (enp89s0 is for LAN and enp87s0 is for WAN)

                    Looks well.

                    Did you disable hardware checksum offloading?
