Windows FTP clients through Linux Firewall
I was hopping that somebody could help me with what looks like a firewall issue on the clients side.
We run an FTP server in house and it works for most all people trying to connect
The clients having trouble are ones running Linux (specifically redhat 7.x and above) and using windows boxes to connect with ftp clients to our server.
If the clients uses passive mode they connect OK but can't do things like create directories or upload files. Change directory seems to work OK.
If they use active mode they can't connect at all or have great troubles doing it.
I have ip_conntrack_ftp module running on their end so that can't be it. We even opened them up the ports quite a lot and still no go.
If I run an FTP session from that Linux box it connects perfect so I am assuming it has something to do with either the client OR IPTABLES.
However here is the wierd part. IE doesn't work, Command line doesn't work, BUT WS-FTP LE works awesome. Not sure what it does special but it works. Problem is that people won't just use that. They want their stuff to work.
