Hmmm that is odd, I have a less powerful FW based on Mandrake 8.2 that can 
happily pull down full ISO files at up to 600KB/sec via my cable modem.

Perhaps it is the kernel version you have, do you have a default 
uniprocessor kernel you can boot to see if the problem still occurs?
What did you build your FW and NAT rules with?
Are they complex?
