      @NogBadTheBad yes, all seems right. But still it does not work.

        Post a screen shot of your NAT rules and your LAN rules.

        You can just drag and drop them into the chat window.

          @NogBadTheBad NAT outgoing:

          nat.jpg

          The last mapping is what I added as workaround.
          Previous two are specific rules (working well) for two specific hosts in the LAN that need specific outgoing IP address.

              Curious why do you have 2 specific IPs in your auto outbound nats? 10.77.36.1 and .5

              What specific IP of client where you pinging from to 1.1.1.1 when you saw the outbound from 0.0.0.0?

              And your hybrid, so you have specific vips on your wan?

              Trying to figure out how your auto rules match up to your networks.. From your rules I see only 2 interfaces. So that would be 2 networks in auto. If it was showing your 2 ipsec, why do you only have 3 there should be 4?? And if the singles are your ipsec? Where is the 3rd range coming from..

              So yeah a bit confusing...

                @johnpoz I was pinging from pfSense itself, not from a client. From clients works.

                Yes I have some additional VIPs

                Yes I have two LANs + two IPSECs. LANs are 10.77.32.0/26 and 10.77.32.64/26. 10.77.36.1 and .5 are IPs on the point-to-point IPSEC tunnels. 172.30.98.0/24 is a subnet on the remote side of IPSEC (this is strange, yes).

                However as I said the problem is not from the connected networks. The problem is only from pfSense itself.

                    @Topogigio said in pfSense sends packet as 0.0.0.0:

                    but is seems having trouble connecting to Internet.

                    In what manner? Are you saying it can not check for updates? Unbound is not working... What is not working.. Other than when you do a manual ping, you say you see source of all zeros? When you don't pick an interface?

                      @johnpoz I noticed the problem because it was unable to populate the available package list..
                      So I noticed that it was unable to resolve DNS, then that was unable to ping, and so on.
                      After the outpoing NAT rule I added as workaround all started to work.

                        so when you remove that rule, it doesn't work anymore? Or maybe unbound just had an issue? If you can not resolve.. Did you see dns traffic going out with all zeros as source?

                          1. You should never have an outbound NAT rule with a source of any -- fix that before anything else. You are in hybrid mode so it's unnecessary anyhow.
                          2. Let's see the pcap, or a screenshot of it loaded in wireshark
                          3. What shows up in Diagnostics > States for the traffic that is sourced as 0.0.0.0?

                          The last time this happened there was something unusual on the user's setup, though I can't remember what it was. I want to say maybe it was an IPv6-only IPsec VTI instance but I'm probably misremembering.

                            @johnpoz If I remove that rule, it does not work anymore. If I remove that rule I see traffic (ICMP request for example) from pfSense with 0.0.0.0 as source. Only traffic from pfSense itself, not traffic from other hosts routed through it.

                              • I know it. I added it as workaround, without that pfSense is unable to contact the world to resolve DNS or download updates.
                              • sorry, a pcap from where? I have access to pfSense and nothing else on the external side.

                              From the pfSense:

                              PING 8.8.8.8 (8.8.8.8): 56 data bytes

                              --- 8.8.8.8 ping statistics ---
                              3 packets transmitted, 0 packets received, 100.0% packet loss


                              15:37:32.819751 IP 0.0.0.0 > 8.8.8.8: ICMP echo request, id 32851, seq 0, length 64
                              15:37:33.830224 IP 0.0.0.0 > 8.8.8.8: ICMP echo request, id 32851, seq 1, length 64
                              15:37:34.840837 IP 0.0.0.0 > 8.8.8.8: ICMP echo request, id 32851, seq 2, length 64

                              states: I cannot find anything related to 8.8.8.8


                              I have IPSEC VTI interfaces, but I'm sure that the problem has started AFTER I configured them (because I required OSPF so I installed the package after the VPNs were connected. However can be something there, I agree. But I cannot understand why and what..

                                No states shown for 0.0.0.0 either?

                                    Show the entire output of ifconfig -a and netstat -rn.

                                    Something is broken in your setup and it's not NAT. The NAT is hiding the real issue.

                                        Were you able to resolve the issue? I ask because I have a similar problem but specific to a VPN VTI. At my home, I setup an IPsec VTI connection to a fresh EdgeRouter. My Local/Remote subnet is 192.168.51.1/30. However, I noticed the P2 negotiates 0.0.0.0/0 for local/remote.

                                        With Static routes setup, my PC can ping the router and connect to anything on the internet. Exactly as I want and expect. However, pfSense cannot ping. Packet capture shows exactly what you have as 0.0.0.0 source and therefor fails.

                                        This wouldn't be a huge problem except that Gateway-Monitor is broken because it can't ping. Now I realize that without GW-Mon, Firewall rules that have a specified GW get skipped. Even when GW-Mon option is disabled and is supposed to be treated as "always online".

                                          @Ziomalski said in pfSense sends packet as 0.0.0.0:

                                          I noticed the P2 negotiates 0.0.0.0/0 for local/remote.

                                          That is normal for VTI and not related to this isssue.
