Description
Excuse me for my english.
I realize a tpdump capture to describe my problem with FileZilla Client 3.3.3
When i realise a upload, passive mode and keep alive option, of a large file, the transfert broken all 5 minutes. I found that it's my firewall who send me a RST packet. After analyze tcpdum capture between client and server, i see 2 connexions data and one connexion that not use "keep alive" command and my firewall with default timeout (5mn) on all session broken this session.
I add a files:
- tcpdump file (client.cap) realize on client
- filezilla.log: log of FileZilla Client
- analyze.log: my analyze of tcpdump capture "client.cap"

Your firewall is broken. A good firewall (or router for that matter) does not drop a connection unless it has been idle for more than 2 hours and 4 minutes. 2 hours is the minimum allowed TCP keep-alive interval and 4 minutes is the packet timeout.
See http://tools.ietf.org/html/rfc5382 for details.
