Upload Problem w/Bullet Proof ftpd 2.15

[dougk_2]

When I upload several files to subject ftpd, the upload hangs after each file has completed. Then FlashFXP disconnects (connection lost), reconnects and uploads the next file. I have PASV enabled since there is NAT on my end. Without PASV enabled, can't even get a dir listing from the remote site.

PC running FlashFXP is in the DMZ on my NAT network.

Is this a known problem with Bullet Proof ftpd? Ideas anyone?

either your 3com router or ZA firewall or router/firewall on the server side is closing main connection during long(..ish) file transfers.

on Proxy/Firwall/Ident tab, try to enable "send noop during transfer" option.

or better yet, look an option in 3com router or ZA to increase 'idle connection timeout' value. it might not have exact same name but should have similar meaning..

Thanks for the pointers. I don't see any time-out configuration for ZoneAlarm or the 3COM Router. I will try a different FTP client on this site to see if the symptoms change.
