[expert] How to limit the ftp service?

[Leopold Palomo]

Dear people,

I have a box connected to external net, and a internal net. Typical
configuration of a box giving services to a internal net as firewall and
gateway from the external net. The question is that we have a ftp
service, but we would to limit this service to the internal net, and I
don't know how to do it. Maybe it's very simple, but I don't know how.
Any ideas?

Best regards,

Leo
