Default Serv-U configuration problem

I'm attempting to configure our site to allow fxp traffic. We are running Windows 2000 NATed behind a firewall. FTP Server is Serv-U v. 4.0

Serv-U configuration:
PASV: (force routable IP in passive mode. Ie: set passive reply IP to real ip address, not natted one)
use passive ports 2000-2010

Firewall Allows port 21, 2000-2010 and NAT's to the ftp server.

I can ftp successfully directly to the server, however, errors when attempting site to site transfers.

"could not open data connection"

Any suggestions are welcome.

Jeff

Hello,

I suspect the problem might be the NAT firewall. NAT and FXP do not work very well together.

If this is the case the only solution would be to reconfigure the ftp server on a port other than 21. By running it on a port other than 21 you disable the NAT ftp extensions (although, there are some firewalls that will monitor every port for the ftp protocol, in which case FXP is not possible)

Default NAT Firewall

The firewall I'm using right now is just a linksys cable/dsl firewall/router.. I don't think that it does ftp proxy, however I will re-configure to another port and give that a try.

My biggest worry was that I had somehow missed a configuration setting within serv-U.

Thanks.

Jeff
