      perhaps this is why i can not access my modem any more? (using these instructions from the wiki)
      https://doc.pfsense.org/index.php/Accessing_modem_from_inside_firewall

      If so, is there a simple alternative?

        im rolling back to 2.1.5, the reason why i do NAT on 2 interface because i have 2 different  WAN, which both have an public ip, and i use them to publish my website on both wan interface.

        is there any update about this problem? is it solve yet in 2.2?

          I have 3 wan outputs with public IP. NAT does not work, inbound one WAN and exits on the second - the default GW. I went rolling back to 2.1.5 also.

            Anyone having this problem, if you could post your ruleset (/tmp/rules.debug) it may help. Feel free to sanitize the IPs but don't erase them (change the numbers to something else consistent).

            Looks like there is something with reply-to and/or route-to that isn't quite right. There is at least one similar ticket – https://redmine.pfsense.org/issues/3760 -- which may need commented on and reopened if it is still broken on current snapshots.

                i cannot give the debug because I've already revert back to 2.1.5, and since pf is my only fw, and is being use in production site, so i hope someone kindly test it in 2.2 latest snapshot to give the answer is this problem still exist or not.

                thank you.

                    Hi everybody,

                    this is not only a NAT problem.
                    It seems that the routing in general does not work properly with multiwan. (in my case WAN_KD=cable router, WAN_TO=PPPoE modem)
                    I'm running the Oct 03 10:14:50 CDT 2014 BETA, but also had the same problem with a previous version (Oct 01).

                    I can't even access the pfS Webgui from the WAN_TO side, although in the firewall log the request is shown as PASS.

                    My config:
                    set optimization normal
                    set timeout { adaptive.start 0, adaptive.end 0 }
                    set limit states 198000
                    set limit src-nodes 198000

                    loopback = "{ lo0 }"
                    WAN_KD = "{ re0 }"
                    LAN = "{ re2 }"

                      I can confirm, I am having the same issue using the Oct 4th 64bit build. I can provide configurations if needed but I know I have configured everything correctly and the firewall blocks show no blocks. Downgrading back to 2.1.5 fixes the issues with the exact same configuration file. Just to give an over view of what I did.

                      created a rule under lan to have my plex machine use the second WAN.
                      Created a NAT (port Forward for TCP 32400) to plex machine
                      Rule was automatically generated.

                      Some fixes that I have found:

                      Changing default gateways to second WAN (Puts everything on second WAN), Not the desired behavior
                      Downgrading to 2.1.5 (everything works as expected)

                      I have this running on my home router so I can flash firmware again if Needed.

                        Actually seems that the one that have posted here have some issues in their configuration.

                        They have set a generic policy routing rule on their lan which overrides the reply-to(NAT of their OPTx) tha would make things work.

                          Hi Ermal,

                          on my Dual WAN (WAN1 = Cable Router, WAN2 = PPPoE Modem) installation I successfully can ping each WAN IF.
                          But I only can reach pfSenses WebGui or anything else on the current Default Gateway.
                          By current I mean, that if the default Default Gateway (WAN1) is marked as down (unfortunately still way too often false alarm by apinger) then I am able to reach the WebGui via WAN2.

                          I followed your suggestions, switched to manual outbound and added the propsed rule on top of everything, but that doesn't change anything.

                          Has anybody had success with this workaround?
                          Any other suggestions to make it work?

                          Thanks,
                          Harry

                          Edit:
                          Ermal in my case, you're right. I've policy routing on lan to a failover gateway group. That same scenario used to work fine with 2.15

                            Excuse my ignorance, but I can't quite figure out if there is a resolution to this yet? I see from Gloom this should be working if you set manual NAT rules on the OPT1 interface (not sure exactly how to, or what this means?).

                            Also, ermal suggests that the problem is that we're using a "generic policy routing rule" - and this is overriding the reply-to. Again, I'm not exactly sure what is meant by "generic policy routing rule" and if there's anything we can do to work around this?

                            I have run Wireshark on the NAT target machine, and whilst I don't understand what I'm looking at, you can clearly see that the http request I am making to the NAT forwarded port (from an external network) is hitting the target machine, so it does seem to be the reply that is getting lost somewhere.

                            My setup

                            WAN = DHCP client
                            OPT1 = PIA VPN

                            I have set-up forwarding via Firewall > NAT and manually created a floating rule for TCP/UDP traffic on OPT1 coming in the my target IP.

                            I have two LAN rules, the first is for target machine and sets the default gateway as OPT1. The second is for all devices and has the default gateway as the router default (which would be WAN).

                            The floating rule seems to make no difference, I see the traffic within Wireshark whether or not the floating rule is enabled.

                              It's not working, none of the workarounds are worth trying (short of for experimentation purposes if you want). This is the bug:

                                      Yeah it should be on that build or newer.

                                        Unfortunately, this still doesn't seem to be working for me. I've tried used the automatically generated linked rule and manually creating a floating rule, but nomatter what I try it is still not working for me on the October 16th 09:56:37 version.

                                        Is there anything else I should be looking at?

                                          Follow the bug report also: https://redmine.pfsense.org/issues/3760
                                          On that, cmb indicates he has done some testing and it is still not fixed.

                                            I have already commented on the bug report too, I just didn't want to get too 'chatty' on there, because it seems the folks on there have done some pretty advanced diagnostics and I didn't want to distract from the good work they were doing :)
