Not true. Any routing algorithm takes longer because they are by
definition a "fuzzy match." The fastforward algorithm is not

Any indirect route via the opposite end of a point-to-point connection.
Right?

It kinda sounds to me like the improved speed you are getting is
from reduced latency rather then from higher available bandwidth.
You may be able to get the same result by increasing the TCP window
size on source and destination. The default is only 16K (on FreeBSD
boxes), 8

right, i got the same feeling. only 550KB on a 10MBit ethernet is
kind of slow anyways.

I will take a look and see if I can get a panic message later on,
unfortunatly the one box that I have running forwarding is a highly
important system that I cant afford downtime on, and most of the time when
it panics Im working on it remotely, but it definatly panics and the box
reboots.

Another couple of 100k/sec per connection.
When I was running as follows:
10mbit network -> pix -> freebsd gateway -> internal network (100mbit)
with 100mbit ethernet on the fbsd gateway, 10mbit up to the gateway (there
are routers inbetween the pix and the gateway), and 100mbit on the

from what to what ? sounds like a 5% improvement or even less...

Hi All,
I posted this a coupla days ago and just thought I would ask again in the
hope that someone had encounted something since then.
Has anyone here tried setting net.inet.ip.fastforwarding on in a high
traffic enviroment?
This setting DRASTICALLY speeds up transfers between boxes talking t
