Not by looking at the packets that pass through the firewall, if
that's what you're asking.

You can set up a web/ftp proxy in the internal network, and only NAT
packets from that machine at the firewall, with everyone using that
proxy to download files.  This way anyone not using the proxy will not
have any way to download files, and the logs of the proxy will tell
you what you want to know.

But this creates one more single-point of failure, since if the proxy
fails, down goes your Internet connectivity through the firewall too,
so you might not like this `solution'.

BTW, this is only marginally related to FreeBSD security, and you
should really post such questions to freebsd-questions. (The Reply-To
