I'm trying to forward port to my VSFTPD server running TLS/SSL. I have open pasv port 9970 - 10000 on trigger port option. I can se them with winscp and ssh. But can't connect from outside. When testing inside LAN it's working and I can se ports 9970 - 10000 be used. This make me thinking does triggered port forwarding works? Have someone used this option and have it working? I have tried to load nf_conntrack_ftp module but seem missing !?
