      Hi everyone,
      I've had issues with my recent migration to a virtulized pfSense installation as my main router. As you can see in the included screenshots, the gateway is online and I am able to ping it from my workstation but even though I can ping the upstream gateway, I have no internet. This is my second attempt at configuring pfSense from scratch.

      Network setup:
      FTTH --> ONT(bridge mode) --> NIC1 on server --> Proxmox bridge vmbr1 --> WAN pfSense VM --> (LAN)vmbr0 --> NIC2 --> Mikrotik 24port 2SFP+ switch.

      pfSense version: 2.5.1-RELEASE
      Proxmox version: Linux proxmox-ve 5.4.106-1-pve

      Hypervisor network config:
      proxmox-network-config.png
      VM config:
      proxmox-vm-hw.png
      proxmox-vm-options.png
      As you can see, I even tried to setup the VM with a 30 second start delay after boot.

      pfSense dashboard:
      pfsense-dash.png

      System > Routing > Gateways
      system-routing-gateways.png

      Interfaces > WAN
      interfaces-wan.png

      Interfaces > PPPs > PPPoE
      interfaces-ppps-pppoe.png

      Logs > gateway
      logs-gateway.png

      Logs > routing
      system-routing-logs.png

      Diagnostics > Routes
      diagnostics-routes.png

      Log > PPPoE
      pfsense-PPPoE.txt

      Ping log from my laptop
      ping.txt

      This configuration sometimes works after changing random settings and reverting the changes while doing plenty reboots.

      Please ask if you need more logs.

        Hi,

        Is the default allow rule set?

          Hi, yes I do have an allow all rule enabled on all LAN interfaces.

          Note: I do have pfBlocker installed and configured but have since disabled it completely.

            This should not be a problem.

            but...

            Resolver and or forwarder? settings are correct?

            what this shows for example:

            a483e552-5e3e-442f-8d69-98ffcd73b482-image.png

            and / or

            +++edit:

            jah,.... and why are you disabling the GW monitor action?

            +++edit2:
            note, you should see something like this...

              If I include the @ 1.1.1.1 it gives an error(no route to 1.1.1.1), without the @1.1.1.1 it resolves bbc.com via unbound.

                One of the troubleshooting steps I tried, have since enabled it again without success.

                  gotcha... - you have no DNS resolution at the moment
                  Okhay, I show you.... 😉

                  you do not have to use CF DNS - choose what you want

                  642528d6-ad37-4812-80ac-cbe5491f1db2-image.png

                  1. network interfaces to the internals (LAN, OPT1, OPT2, etc,)
                  2. Outgoing Intf.s (WAN, WAN2 or VPN intf., etc.)

                  +++edit:

                  Unbound in forwarding mode!

                  pls. on GENERAL TAB + DNS servers + DNS behavior = USE REMOTE DNS SERVERS!!!

                  Cats bury it so they can't see it!

                    CF is my 2nd choice for DNS provider:

                        Yes its enabled (should it be enabled or disabled? I assume it should be enabled)

                          don't touch it 😉
                          this is correct if you want to use third party DNS (like CloudFlare 1.1.1.1) instead of root servers

                          the problem will be with this: ( System / General Setup)

                            @daddygo I just did my 7th restart of the ONT and re-socket of the Ethernet cable, internet is working now. No idea what it could be, maybe a faulty ONT or NIC🤔

                                    I guess the DNS server override is checked

                                    Nope it isn't
                                    The DNS Resolution Behavior is also set to "Use remote DNS servers, Ignore local DNS"

                                    this will help you in many ways
