dummynet question

[Ganbold]

Hi,

I'm using FreeBSD 5.2-current machine for firewall. It is configured as a 
bridged ipfw2 firewall.
Also this machine works a a traffic shaper using ip dummynet features.
I'm trying to limit bandwidth for some particular application, for example 
eMule p2p application.

I'm doing it in the following way:

# eMule
${fwcmd} pipe 59 config bw 256kbit/s
${fwcmd} pipe 60 config bw 256kbit/s
${fwcmd} add 80 pipe 59 ip from 202.179.x.x/19 to any 
2323,4242,4243,4661-4672,7700-7800 in via fxp1
${fwcmd} add 81 pipe 60 ip from any to 202.179.x.x/19 
2323,4242,4243,4661-4672,7700-7800 in via fxp0

Am I doing right?

tia,
