Hello everyone,
Could you please help me with settings of pure-ftpd.

Here is my actual solution:
I have got linux (debian 7.1 wheezy ), where I run pure-ftpd, created virtual users, folder for ftp. I also install openssl, create private certificate for tls. All seems good.

When user connect from internal address in passive mode without TLS - its working fine.
When user connect from internal address in passive mode with TLS - its working fine.
When user connect from external address in passive mode without TLS - its working fine.
When user connect from external address in passive mode with TLS - ftp doesn't work, because ftp server return to external client local ip address. And client doens't know this address.

I also tried solve this problem to create conf file in /etc/pure-ftpd/conf/ForcePassiveIP ,where is written external address. But when user connect from external address he got external address what is fine, but after he got another error with connection. And this waz I think is not good, because users from internal network will not be able to connect ftp, because they will get external address from ForcePassiveIP conf file.
Maybe I can make two ftps server with different settings, but I think its not optimal. Could you please help me ? lw: I am beginner with linux, so if you have any solution could you please more expand for me ? Thank you very much.
