      @toddehb said in LAN has no connectivity:

      I have enabled LAN2WAN outgoing NAT.

      That shouldn't be needed, pfSense add necessary rule automatically.

      Do you see a proper default gateway in Status > Gateways?

      If so, run a packets capture on WAN while you try to ping 8.8.8.8 and post, what you get out.

        Yes, default Gateway is WAN DHCP.

        Packet capture gives this, when pinging 8.8.8.8

          So you can see ICMP requests and replies on WAN. Did you ping from the LAN machine? If so, I can't believe that you get 100% packet loss.

            yes, pinged from the LAN machine.

            f87aa309-98cd-4e4b-8c42-ec916d8f03ec-image.png

            There is no local firwall ( iptables etc. ) running on the client

            ICMP request and replys are hitting the pfsense so I have no clue where else packets could get dropped, rejected or whatsoever

              Did you state a gateway in the LAN interface settings?
              If so you should remove it.

              Take a capture on the LAN interface while pinging to see if the response go out out properly.

                Huh? There is nothing to do for this pfsense behind your 1st pfsense to have internet access. If its gateway is your first pfsense.

                Unless you messed with the 1st pfsense outbound nat..

                To your 1st pfsense, this 2nd pfsense is no different than any other client on your 1st pfsense lan.

                  No gateway defined on LAN

                  Outbound NAT rules where created automatically

                      @toddehb ok - not sure how I read that hehehe

                      But your device is just on pfsense lan.. There is nothing to do.. - what did you mean about you enabled lan2wan outgoing nat?

                      Do you have any rules on floating?

                          @toddehb what is your wan IP on your pfsense, its not a 10.x address itself is it?

                          What I would do is sniff on your pfsense wan while you pinging from this client to say 8.8.8.8 do you see that traffic going out your pfsense wan?

                            no, look at the screen witch icmp packets. I obfuscated the ip a little bit

                                So the responses go out on LAN properly to the VM IP.

                                Check if the IP has the correct MAC in pfSense ARP table in Diagnostic > ARP.
                                Otherwise I can only imagine that there goes something wrong on HyperV.

                                  @toddehb so what is not working - looks like both your pings are working from that trace. I see both a ping reply from 8.8.8.8 and dns reply from the 4.2.2.1 etc.

                                    The console is not showing any output when pinging. NSLOOKUP does not lookup and apt update eg. is not working. The system does not seem to have internet conenction.

                                      @toddehb but from your sniff pfsense is sending on the reply to your ping and to your dns query.

                                      So whatever the problem isn't a pfsense issue, it did what you asked, it sent on your ping and dns.. And when it got a reply it sent it back to the client that asked..

                                        Yes, but cannot figure out what is going wrong. Did a reinstall on that VPS, same issue. Will contact support of Hoster. Maybe they know what is going on

                                          Just want to update all on the solution. My hoster had some ebtable rules active which were actively blocking the traffic. They disbaled them and now everything is going smooth :👍
