	I trying to set up an Amiga 3000 running 1.0 as a gateway to a
subnet, but having extreme difficulty.  I'm not sure if the problem is 
with the way I am configuring things, or a problem with netbsd (or the routed
that comes with netbsd).

	The gateway has an ethernet interface ( on the 
subnet ( with a netmask of  When needed,
I also add the SLIP link to the rest of the world, interface sl0, IP, dest, netmask

	The SLIP link works fine, but noone else inside the ethernet subnet 
can reach either side of the link (pinging from another
host on the ethernet is futile).  What's really odd is that pinging from the gateway results in "host is down"!!  I can't
even reach my own interface?  I'm starting to think that there may be 
something I don't know about PtoP links or something wrong with the
system (GATEWAY is configured in the kernel).

	Another problem I face is with routed.  I figured that I should run
an active router to let people on the rest of the net reach the machines
inside my subnet...  But, routed will not monitor for new interfaces unless
the interface is configured down when routed is started (at least that's
what I gather from a quick look through the sources).  So, I tried to 
set up /etc/hostname.sl0, with the option "down" included.  Well, all of
a sudden I start getting "arpresolv: can't allocate llinfo" on the tty, just
as soon as routed starts - and 'ifconfig sl0' reveals that the interface is 
marked as up!
	So I removed hostname.sl0, and rebooted, but I was still getting
the error from arpresolv until I killed off routed.

	Now I'm back where I started, except that I can't run routed until
I start the slip connection (i'm guessing it's related to the fact that 
/etc/gateways now includes my SLIP server, why that keeps it from allocating a 
llinfo is a good question, though).

	What's really odd about all this is netstat -r:

oedipus is the slip server, kuru-net is the subnet, lupus is a machine on the 
subnet, and kuru-gw is my slip interface.

	I'm really not sure what all the "link#1"'s are, but I know
that kuru-gw is _not_ on le0 - it is sl0.

	Does anyone have any idea what I am doing wrong, or what is wrong?
I'd really appreciate any help or even just clues.
