Because emule bittorrent seems to use almost any midrange port greater 1024,
I use the following rules to limit the bandwith for such tools for a single
machine very effectively:

        #${fwcmd} add count all from any to any via ${oif}
        ${fwcmd} add pipe 3 tcp from ${lupo} to any 1024-32768 via ${iif}
        ${fwcmd} add pipe 4 tcp from any 1024-32768 to ${lupo} via ${iif}
        ${fwcmd} pipe 3 config bw 64Kbit/s queue 10Kbytes
        ${fwcmd} pipe 4 config bw 160Kbit/s queue 30Kbytes
