FTP timeout problems

Hi to all!

This is my first mail to the mailing list, and I hope not to ask something yet
asked, but I read the FAQs over and over and I didn't find something regarding
the problem I have.

Since I have installed Squid 2.x I have problems with ftp servers, and now
that i'm using 2.2PRE2 I have big problems....

I cannot connect to any ftp server (even on my LAN). Making the debug level
for FTP higher shows me that the connection starts (and I can see it in
netstat -t output), but after a while it tells me that the connection timed
out (in cache.log, in the browser it tells me that there are problems
contacting ftp://[no url]).

I'll attach relevant parts of my squid.conf and I'll tell you that the
computer running squid is a P133 with 128 Mb ram and 2Gb disk for the cache.

Linux 2.0.36 is my OS.

Plz, help
