FTP with a Norton Firewall?

When attempting to connect to my server, I get the following:

Resolving host name ftp.my server.co.uk...
Connecting to (ftp.my server.co.uk) -> IP: some.ip.address PORT: 21
Connected to (ftp.my server.co.uk) -> Time = 0ms
Socket connected waiting for login sequence.
Cannot login waiting to retry (5s)...

When I disable my (Norton) firewall, It connects and allows me to FTP to my hearts content. However, I am concerned at the security risk :twisted: to my home PC.

How should I configure either SmartFTP or Norton to allow the FTP with the firewall running?

I am running on XP pro and have disabled the windows firewall.

Any help will be much treasured .

Regards,

Pete.
