Tall ships (porthole)

On IPCop and traffic shaping

Today's discovery: IPCop's traffic shaping is really odd.

About a year ago, I set up traffic shaping at 10240 kbits/sec down, 448 kbits/sec up and forget about it.

Today, I was puzzling over why the slower ADSL2+ connection (3.5Mb/s down, 1.2Mb/s up) actually performed better than the ntl cable (rated for 10Mb/s down, 512kb/s up, in practice about 4Mb/s down) and realised that all testing with ADSL2+ had excluded the IPCop firewall. So I disable the traffic shaping on a whim, and download speeds doubled.

Testing with Virgin Media's FTP server, I just managed to download a 252MB file in about 6 minutes 30 seconds. That's 6.55Mb/s. That's about 2Mb/s more than we generally get from this connection.

Right, anyone know how to set up IPCop traffic shaping such that it doesn't suck?

If all goes well, this should be posted from my laptop using Vodafone's GPRS service.

Buwhahaha! Nowhere is safe from my ramblings!

Edit [from the land of the wired]: to make this post cost me tuppence! Now all I need is to make the email client on the phone behave, and then all I'll need to post is a cellphone signal.
