Port Forwarding to FTP Server in lan

Installing and Using OpenWrt
1

This is what i have:
Archer C7 v2 with LEDE Reboot SNAPSHOT r4590-b4ce088 / LuCI Master (git-17.194.28316-2224714) Kernel Version 4.4.74

Everything works fine, except port forwarding to my linux proftp server. I have set up a port forwarding ssh to my x2go server...works, also http port 80 to my apache...works. Only ftp protocol does not work. With stock firmware ftp port forwarding works fine. Should i switch back to stock firmware ore is there a solution with lede firmware?

This is the error message from WinSCP:
Server sent passive reply with unroutable address 192.168.x.x, using host address instead.
Übertragunsgtunnel konnte nicht geöffnet werden. Grund: Es konnte keine Verbindung hergestellt werden, da der Zielcomputer die Verbindung verweigerte.
Konnte Verzeichnisinhalt nicht abrufen

Sorry for german. I am living in austria.

Hi @hepue,

The router is not running an FTP server itself?
All your servers have the same mask?

I have an Archer C7 v2, with many ports redirected and I have no problems.

Hi Klingon.

Thank you for your reply Klingon. I have no FTP running on lede. My apache, x2go and ftp server runs on the same machine with different ports. Sorry guy`s, lede is verry powerful, but now i am back on stock....

Wow, that went fast... As far as I can rebember, for redirecting ports behind a router, you need to forward ports 21 and 20 (control connection and data connection). Maybe you need to install some *contrack* package as well.

ernsthaft? Du wartest keine Anwort ab und wechselst schon vorher zu Herrstellerfirmware zurück? Du gibts uns keine weiteren Informationen, z. B. wie deine Firewall Konfiguration aussieht und so.

really?

Hallo rj45.

Bin wieder auf LEDE mit meinem neuen Router Linksys WRT1900ACSv2. Habe das Problem gelöst!! Musste nur noch das Paket kmod-nf-nathelper installieren. Siehe FS#523 - Problem with FTP (Pure system after upgrade from OpenWRT).
