Hi, I think I need to put in a ACL forwarding or allowing ftp traffic. Not what Rules are required.

My FTP server is a windows sbs 2003

I don't think this is the issue as I've not set the firewall to low so the config now has the line ... ip inspect name SDM_LOW ftp

I know its obvious but is the FTP Server up and running and can you connect to it from inside your network.?

Is your ftp server running with passive mode? If so, You may need a static NAT to accomplish this. Because the server will tell you to randomly use a range of udp ports(1024-65535) to send data. It's not easy to define NAT statement including udp ports.

The FTP Server is running as I'm able to access the FTP Server from inside the Network.

I have nat in place

ip nat inside source static tcp 20 xxx.xxx.xxx.58 20 extendable

ip nat inside source static tcp 21 xxx.xxx.xxx.58 21 extendable

what's the exact error you got? Did you pass the authentication process? Can you send/receive any data to/from the server?

This is the answer but it came a day late as I had to pay 75euro for the answer.

There was I thinking it was a cisco problem but it was an IE issue.
