Hello, i'm trying to use ftp with FileZilla Server. I set forward port 21 from wan to my local machine (192.168.1.2). FTP uses passive mode, but i can't connect from outside to it. What should i do besides forwarding port 21?
need to open a passive port as well, might be enough to install the conntrack package and/or nathelper.
or switch to port mode.
My port forwarding screen:
and here is installed software conntrack
And what you mean switch to port mode?
Is the same 60k port range defined in the ftp server?
There is a possibility that privileged ports (below 1024) are blocked by the ISP.
Try using something like 8021 externally.
No, all ports works, i used TP-LINK 1043 before, all works.
Well, then I would check if any packet with destination port 21/TCP is visible with
tcpdump first on WAN and then on LAN interface.
