This cannot be done by the firewall. SSH is a opaque encrypted tunnel.
You have to handle this outside the tunnel part. ie. at the client or
Preferably at the server end, where there is more trust.
But how do you give shell without the capability to transfer a file? You can't,
unless you remove the file transfer parts of the server and create a restricted
shell for the user.
$ tar -cf - dir-of-files | ssh servername "tar -xf -"
$ ssh servername "cat > file.txt" < file.txt
