In a post I saw in firewalls-digest, you write:

The Raptor Eagle firewall (not a screeneing router, but ...) lets you
apply "Service Limits" to the rules governing connections. Some of the
Service Limits are: "notelnet", "noftp", "ftp.getonly", "ftp.putonly".
"ftp.getonly" does what you're looking for. See http://www.raptor.com
for more information.
