Hi there.
A colleague of mine has recently stubbled on a curious problem.
He works on a embedded device which is connected to a USB ADSL modem.
When the kernel is build without any IP filtering the transfer rate is OK (~8.5Kbyte/sec).
When he enables CONFIG_NETFILTER & CONFIG_NAT the rate drops at ~4.5Kbyte/sec without him enabling any rules.
The system load does not appear to be a problem.
It is quite possible that there is a problem with the (proprietary) ADSL driver, but I was wondering if someone else had some similar problem in the past and could offer some advice on how to track it down.
