I'm a bit confused coz of the following script i wrote.
i = build up a=20 server-router-client model to check the script.
i configured no = ingress but=20 the script limits the bandwidth to about 250 kbyte/s.

all the time i'm getting wrong bandwidth limits.

anyone an idea what the problem could be ?
maybe something wrong = with the=20 script or maybe not enough power of the hardware (P2 300MHz; 128 MB RAM) = ?
