Re: [fw-wiz] Slow FTP transfers



Your problem could be due to your firewall blocking the IDENT protocol

Have a look at this link:

It could also be related to PTR records for your DIP Pool (but highly
unlikely):

Maybe there's some checks that works better or worst depending if the
ftp session is passive or not.

I'm having an issue when ftp'ing (default port mode) large file

gets real slow and at times just timeouts.

Any thoughts will be great.

Any sort of packet shaper/QoS device between the endpoints?
