[squid-users] Native FTP relay: connection closes (?) after 'cannot assign requested address' error

[Alexander]

Actually, a PASV-handling logic looks a bit strange to me. In
Ftp::Server::handlePasvReply() there is a comment:

"In interception setups, we combine remote server address with a local port
number and hope that traffic will be redirected to us."

How is it supposed to work? A client receives server's IP and squid's port
and tries to make a connection, which obviously ends with ECONNREFUSED. I do
not have any idea on how a traffic could be redirected to squid (redirecting
everything from A to B is not an option). Also, why squid needs to intercept
a data connection?

If I hardcode one of squid's IP in handlePasvReply(), everything works fine.
However I am not sure if it is a correct way because a client opens a data
connection not to an FTP server...
