SubjectBUG REPORT: Massive performance drop in routing throughput with 2.4.21
Hello all,

there seems to be a real serious problem with 2.4.21, routing through two
ethernet-devices. After 24 hours of a routing-only box the throughput from
ethernet a to ethernet b decreased to something around 4-100 kByte/sec (100
Mbit network 2 cards ns83820). I had to drop using 2.4.21 on this box because
of this. 2.4.20 is flawless on the machine and ran for around 100 days before
without any troubles. Going back to 2.4.20 cured it.

The box itself:
