networking problem? maybe

If you have more than one computer available, try linking up a switch to
your second Ethernet card and running a test between two machines that
should not touch the gateway. What's your internal LAN speed when the
gateway is not involved? That will tell you whether it's the gateway you
need to look at.
To explain better:
Machine 1 Machine 2
Have Machine 1 talk to Machine 2. What's your speed? If it's significantly
faster, then it's time to look at the gateway. If not, look at the switch.
If it's the gateway, try reconfiguring your gateway so that the (b) ethernet
card talks to the ADSL line and the (a) card talks to your LAN. Any change
in speed? If so, it's probably the card or the config associated with it. If
not, it's probably your routing configuration.
Hope this gives you something to start from!

Subject: networking problem? maybe
i have just installed freebsd 4.9 one of my machies.
This box is configured to be a gateway/router. The install was a base
install, and i recompiled with the IPFILTER options. Ive added the
net.inet.ip.forwarding=1 to my /etc/sysctl.conf.
When accessing the internet (via ADSL/PPPoE) on the gateway machine, my
downloads are very fast, and im very happy.
my problem is that when i connect any computer to this LAN, the speed drops
dramatically. For example: From the gateway machine speed > 90K/s. From
Machine attached to gateway machine speed < 10K/s.
Im not very good with networking, so im not exactly sure how to troubleshoot
this. May someone suggest something for me to check. I would like to keep my
gateway with freebsd. I hope this wasn't too confusing.
