Block Internet expect for FTP

Hello,

I have a iMac that I would like to use as an FTP client for employees in my company.

The objective is to allow users access external FTPs to get some content but have all the remaining internet protocols blocked.

Is this possible? If so how can it be done?


Thanks

Block all outgoing connections except those on port 21. Ask your IT guy to setup this up for you.

You could also look into something like Little Snitch which can give you application specific control.
