Will,

I duplicated your Quasijarus setup as closely as possible - I followed all
the setup instructions on the tavi.co.uk site to the letter, and duplicated
your network setup exactly (save for the fact that my home network is
192.168.1/24 rather than 192.168.0/24).  I am able to ping my local gateway
(192.168.1.1) and use that same IP to resolve addresses but I don't get
responses to external traffic:

# ping www.netbsd.org
PING www.netbsd.org (199.233.217.205): 56 data bytes
^C
----www.netbsd.org PING Statistics----
4 packets transmitted, 0 packets received, 100% packet loss

I can connect to an FTP server on my home network but not to an external
one:

# ftp 192.168.1.63
Connected to 192.168.1.63.
220 aelfric FTP server (Version 6.4/OpenBSD/Linux-ftpd-0.17) ready.
Name (192.168.1.63:root): ^C
# ftp ftp.gnu.org
ftp: connect: Connection timed out

Setting "ifconfig -trailers", which has helped with connection problems on
ancient BSDs before, made absolutely no difference.

So even if you do manage to get to the point where local network traffic is
okay, external traffic probably isn't going to be.  At this point, to be
perfectly honest I think I've reached the limit of how much I'm willing to
investigate Quasijarus, especially as I have determined to my satisfaction
that this is not a SIMH problem.  My suggestion would be to move to an
older version of NetBSD, maybe 1.4 or 1.5, or if you're set on 4.3BSD to
try one of the other variants.  I've never had any networking issues with
vanilla 4.3 or 4.3-Reno.  There are installation instructions at
http://gunkies.org/wiki/4.3_BSD and associated pages, though you should be
forewarned that they are not quite as detailed as the Quasijarus
instructions you found.
