Open Sygate and you should should see the FTP Daemon running as a service. Change it's access from Ask to Allow.
Click on applications and highlight the Daemon. Open the advanced properties (for applications NOT rules) and you can then set which ports, IP addresses, protocols etc that you want it to be allowed to use.
I was told that to allow successful data transfer you must allow 2 ports (one for the data, one for the write back info) but I'm not sure whether this is true or which seconadary port is requried. The best way to find out is to test it
If you want to PM your IP to me I'll be able to test it this morning if you need it.
