I suppose this is a VERY FAQ, but since our news server
is down and I couldn't find appropriate answer in
386bsd-faq.

I'm running a SS1+ with NetBSD-1.2. It has a secondary
ethernet card, and I want to set it up as a network router.
result of "ifconfig -a" is like this.


le0: flags=a863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,LINK1,MULTICAST>
        inet 143.248.173.51 netmask 0xffffff00 broadcast 143.248.173.255
le1: flags=a863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,LINK1,MULTICAST>
        inet 143.248.187.1 netmask 0xffffff00 broadcast 143.248.187.255
lo0: flags=8009<UP,LOOPBACK,MULTICAST>
        inet 127.0.0.1 netmask 0xff000000
sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST>
...

AND, as in 386bsd-faq, I tried "sysctl -w net.inet.ip.forwarding = 1"
and even tried to recompile the kernel, but still it doesn't work.
Some lines from "netstat -rn" are like this.

173.* is the primary net, and 187.* is secondary(internal) net.
there seems to be nothing wrong, but still it doesn't work.
routed is NOT having "-q" option. I even tried "-s -g" option.
nothing works. please help me. I'm in very urgent need.
