      @viragomann:

      If you're pinging from pfSense itself (Diagnostics->ping) there are no firewall rule applied.

      what do you mean with that? sould it work or not?

      Yes this should work anyway.

      @elessargr:

      @viragomann:

      Anyway, it isn't translated to WAN address while your NAT rules are okay. This may happen, if you change your LAN subnet.
      Go to outbound NAT and try click Save button and reboot pfSense and see if it helped.

      This may happen, if you change your LAN subnet. ?????
      save without do any new changes?

      In former versions there were no changes necessary to reset NAT rules. But you may also switch to hyprid rule generation and save it to ensure it is saved.

        on the ping nothing from the lan interface

        I have also change the NAT outbound to Hybrid Outbound NAT rule generation (Automatic Outbound NAT + rules below)

          look for pings to the destination address (8.8.8.8 ). In the packet capture tab you can enter this address at host for filtering.
          The packet capture must be taken from WAN interface. Have you done this above?
          The pings there should come from your WAN address regardless, what's the real source, cause of NAT.

              If this capture is taken from WAN your outbound NAT isn't working. On LAN it should look like this, apart from missing responses.

              Have you disabled firewall and NAT in pfSense? System > Advanced > Firewall / NAT > Disable Firewall.

                  You don't get "DISABLE all packet filtering" ??

                  States turns pfsenes into ROUTER only!!
                  States also turns off NAT

                  That clearly is not checked out of the box… So you must of on purpose checked that... But you don't understand what it says?

                  What is it exactly that confuses you about that box and its wording??  And that is says DISABLE FIREWALL???

                  English is not your native language maybe?  And your putting that into say google translate and its coming out confusing in your language to if that turns on or off the firewall??

                  I don't get it is right ;)

                    If this is unchecked firewall and NAT is turned off. Hence your outbound NAT didn't work.

                    It's unchecked by default, as johnpoz wrote. You may have checked it to prevent double NAT, cause your route also do NAT. If it's possible it's better to turn off NAT at the router. However, double NAT should also work.

                      I dont remember check in it; so I think its check out of the box.
                      now Im confuse because its says "disable firewall  [checkbox]" that means if I check it the firewall is OFF (check=yes, uncheck=no correct?) and viragomann says otherwise.

                      @viragomann:

                      Are you sure? because now its working fine. Im going to firewall->rules-> and I put ICMP allow and its passing. I set it off and its blocking. Before no matter what it was always off; no ping was passing through the lan.

                        That sentence is the wrong way around, it should say:

                        If this is checked firewall and NAT is turned off. Hence your outbound NAT didn't work.

                        As the Greek philosopher Isosceles used to say, "There are 3 sides to every triangle."

                          Yes. Sorry, my mistake.
