The reason that I think it is fail2ban is that if I white-list the ip in fail2ban it works fine, also I can ftp from other ip's even when the one ip is blocked.

but I will also research a bit more into the vsftp setting, if there is a block per IP, thanks for suggestion.

All bans should be logged by default. How do you conclude that it is f2b
that is blocking access to vsftp, when it is not logging that?

I never ran vsftp (or any ftpd for that matter), but when reading its
manpage, the max_login_fails and max_per_ip configuration options could
result in blocking a connection too, based on previous login errors.

Please show logging that supports the fact that access to vsftpd is
blocked by f2b. Maybe you can show the relevant part of iptables -L
output (or whatever blocking mechanism you configured)?
