Greetings again!!
Just a short update.. thanks to very helpful people on this list, I
have been pointed to things i missed in my configuration and changed
the following things:
sysctl net.inet.<tcp/udp>.<send/recv>space=65535
changed my hub to a newer switch and set all nics to autoswich/
autosense again.
This brought a network downstream (internet-->any computer within the
home network) from about 480kbit/sec to about 660 kbit/sec. Thank you
for that!!
Are there any other things I could try? Because I am pretty sure I
have about 1.8 mbit/sec downstream..
I tried tweaking the above sysctl values even more, but that didnt
reap any benefit.
Can I provide you with any other details or configs or whatever of my
setup that might prove useful to any of you?
Thank you for helping me!
Yours,
Christian Fuchs

Greetings everyone!!
I have been using OpenBSD for some time now on my Soekris 4511
router. I have OpenBSD 4.0 installed (off the cd) with all of the
OS on a CompactFlash card which is mounted read-only; I used the
"flashdist.sh" - script rom http://www.nmedia.net/~chris/soekris/ .
I use the system to connect to my isp via the pptp client (version
1.7.1 with pppd, but I also tested version 1.7.0 from the ports
with the user-ppp) and then do NAT for a mac os x and a windows
client behind my firewall. Except that, I only run sshd on the
soekris box.
The hardare setup is as follows: <alcatel_modem>----
<soekris_box>-----<3com 100Mbit HUB>--(Mac, Win, ps2)
Everything works fine but for speed; I would get about 1.8 megabit
downstream from my ISP service, but with openBSD i just get about
400 kbit downstream. I am pretty sure the hardware is not the
problem as the speed is as it should be when I install m0n0wall
(freebsd-based) on the same soekris box.
I tried looking at top for system load, system load is about 0.22,
and the idlce counter never goes down 50% even when I try to use
full traffic. The only thing I can think of to hint at the problem
is the ouput of "netstat -n -I sis0" <with sis0 being the network
port connected to my internal network>

Is the number of Collisions maybe the problem?
As cpu load never reaches 100%, the packet filter can't be the
problem?
I tried searching the web for my problem, but did not find anything.
Do you perhaps have any idea what did wrong or configured
incorrectly?
Please find my pf.conf attached as well:
