Re: [squid-users] Problem with some ftp server from windows client (squid is running in debian)

Just putting this on the squid list
Alceu : Please copy squid-users@squid-cache.org, thnx.

p.s:
I'm not talking about squid at all here. I mean use an ftp client without
squid to try and isolate the problem which I 'believe' to be nat.
