      Hello,

      I have checked the FAQ section as well as a forum search but am unable to find the answer to what is happening in my case.

      I have a static routed Dual WAN configuration that works fine. (see my previous post for setup details if needed..)

      All LAN trafic if routed by default over OP1(WAN2) this works fine. I have also noted that ftp does not work over OPT1, so I have a Firewall -> Rules -> LAN where I have :

      Proto    Source    port Destination Port Gateway
      tcp      LAN net    *        *          21    *
      the default gateway is WAN so that should be ok. After this I have the following firewall rule for LAN:

      Proto    Source    port Destination Port Gateway
      tcp      LAN net    *        *        110    *
      I have this because I want pop routed over the default GW, it work fine.

      Finally I have all other traffic routed over Opt1 (WAN2) , it works fine too.

      Proto    Source    port Destination Port Gateway
      tcp      LAN net    *        *          *  192.168.1.1
      That is my Opt1 (WAN2) gateway.

      But I seem to be missing something in ftp.. it almost works:

      Connected to ftp.test.nl.
      220–-------- Welcome to Pure-FTPd [TLS] –--------
      220-You are user number 3 of 50 allowed.
      220-Local time is now 11:45. Server port: 21.
      220-This is a private system - No anonymous login
      220-IPv6 connections are also welcome on this server.
      220 You will be disconnected after 15 minutes of inactivity.

      ftp> ls
      500 I won't open a connection to 192.168.2.4 (only to 82.215.27.218)
      425 No data connection

      Why is this not NATted?
      In Interfaces -> WAN I have tried both with Userland FTP-procy switched on and off..

      Any help will be apriciated…

        Your  ftp-server doesn't know about it's public IP and is handing out it's private IP to the client. The ftp rpxy usually should fix that if configured properly. Make your ftp-server aware of it's public IP (most ftp servers have a setting for this hiding somewhere). You will need to forward another portrange that the ftp user uses additional to the port 21 to support passive connections.

          Hi Hoba,

          I think you mis understood. I am trying to ftp to a remote site from LAN, so the FTP target server is internet hosted. Just dosbox -> ftp -> open ftp.bla.bla..

          It connects I can login.. but as soon as I do ls.. I get this message back from that remote server…
          Other ftp clients are also unable to get listings from remote servers..

          :'( just makes updating a website compluicated now...

            Ah, ok. I misunderstood something here. I think you are bitten by this bug: http://cvstrac.pfsense.com/tktview?tn=1138,6

            The workaround is in the report. turn the ftphelper on at the internal subnets and place the loopbackrule at every internal interface that needs it. Also try with passivemode if this still doesn't work.

              Hi,

              As indicated I have enabled; removed checkbox at Interfaces-> LAN -> Disable the userland FTP-Proxy application

              Added the following rule, as indicated in the work around, for LAN and DMZ:

              Proto      Source Port Destination          Port        Gateway Description 
                TCP/UDP    *        *  127.0.0.1      1 - 65535          *        FTP fix

              Please note that I am NOT load balancing, just static routing.

              The issue remains the same, I do not know if the following info is of any use.. but just in case.. Total connander ftp client log output. Dos command line ftp message remains the same also.

                  Hi,
                  In passive mode it simply will not LIST.. one can wait for minutes..

                  Connect ok!
                  PWD
                  257 "/" is your current location
                  Get directory
                  TYPE A
                  200 TYPE is now ASCII
                  PASV
                  227 Entering Passive Mode (85,17,3,142,215,115)
                  LIST
                  Cancel pressed!

                  In dos the following:
                  ftp> ls
                  –-> PORT 192,168,2,4,15
                  500 I won't open a conne
                  ---> NLST
                  425 No data connection

                  So any suggestiosn are still welcome.. I am just stuck at this one?
                  If some one is able to ftp tp websites etc from LAN to any internet hosted ftp server using staic Dual WAN please let me know what your settings are..

                        Oh, btw, you have to reset states after you added the loopbackrule. If you still have old states in your statetable and you try to get tot he same server again you will still see the problem. (diagnostics>states, reset states)

                          :-( did that .. even before posting ..  even after the workaround..

                          I did a reboot and that solves it.. as it seems resetting states isn't working.. I have that with rule changes also..

                          Anyway the workaround has solved the main issue..

                          Thanks Hoba ..

                            Oh, then you see the filter_reload bug as well. This has been fixed and will be available as download soon (1.0.1 is in the pipe).

                                I think I have the same problem and even slightly worse  :-\

                                I couldn't connect to any FTP server on the Internet so I added the workaround rule above my Allow All on LAN and redirected it to the default gateway (WAN, I'm loadbalancing on WAN and OPT1). Now I can connect to FTP servers (including passively) but sometimes it can't LIST, and just hang there, regardless of the FTP client. I did a state reset and even a reboot, to no avail :(

                                  Make sure you use "default" (should show up as an asterisk in the rules view) instead of the WAN-IP as gateway.

                                    Yep, that's what I was using. I updated to 1.0.1 and after the reboot it seems to be working now :)

                                    Anyway, if my WAN comes down I'll have to edit the workaround rule to use OPT1 as the gateway, right?

                                      The ftp helper can only be used at the original WAN as it is a userland application that can't make use of the loadbalancer. This is a limitation. Btw, we fixed something behind the scenes, so you should try if you now can do without the workaround rule. Just disable it and try again.
