I posted this in the OSX section:

Whenever I FTP large files to or from my Mac, I get a time out error. It says:

"Timed out. Server closed connection. The server might be too busy."

Small files, say a couple of megs work fine, but it's the large files that fail. This also happens on my Linux box, the two are connected to the outside world through a Linksys firewall/router. Is it the router, or do the machines need to have a file size limit configured somehow?

Anyone have any ideas?

I since have narrowed it down to my Linksys BEFSX41 Firewall/Router. When I connect the cable modem directly to the computer, the up/download completes fine. When going thru the router, it fails the transfer. So. it seems to be the router, possibly the MTU? Any advice?

The router's setup includes the ability to configure it for "passive FTP" connections-using this will often allow the router to be more successful at long FTP downloads.

I think the reason for the problem is that the router loses track of the number of hops between your modem and the FTP site, as long downloads tend to go through multiple paths.
