Server :: Vsftpd: Can Connect Remotely But Not Locally?

I'm running vsftpd-2.2.2 on Slackware 13.1 and I'm behind a NAT with a dynamic IP. I'm using pasv_address, which makes it necessary to have a crontab that checks whether my IP has changed, and if it has, edits the conf and restarts vsfptd. It's hackish but it works. I have also enabled FTPES on the same port that normal FTP runs. I have allowed only the 5001:5003 ports and I am aware that the recommented is 50 ports. However I never had an issue with the transfers since I'm the only user and have at maximum two simultaneous transfers.

I can connect remotely with FTP and FTPES with every client I tried but I'm having issues locally. FileZilla refuses to connect on FTP and FTPES. WinSCP can connect on FTP but not FTPES. Issues are gone if I enable pasv_promiscuous, which the manpage strongly recommends not to use unless "you know what you're doing". I don't. Why is this happening? And, can I fix the local connections without resorting to pasv_promiscuous?

Here is my config and log files from a failed local attempt.

vsftpd.conf

Code:

anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
