[wplug-bsd] Net configuration still not working

[Brandon Kuczenski]

So I am still struggling with this FreeBSD 5.3 router.  Here's the network 
layout:


 		128.2.56.1  CMU-operated gateway (netmask 255.255.252.0)
 		     |
 		     |
 	/-----------------------\
 	|  xl0:  128.2.57.58/22	|
 	|	BSD BOX		|
 	| pcn0: 192.168.1.2/24	|
 	\-----------------------/
 		     |
 		     |  +-------------------- 192.168.1.20/24
 		     |  |			my laptop
 		W    L  L  L  L
 		192.168.1.1/24
 		Linksys WRT54GS

The linksys router has a WAN port (indicated by W - not used) and four LAN 
ports (indicated by L).  It has been told to act as a 'router' rather than 
as a 'gateway'.  I've tried using other plugs and switching plugs.

OUTSIDE: normal operation. I can ping my gateway and google.com from the 
BSD box, and I can connect to other computers via ssh.  Other computers 
can view the webpage at http://leduc.me.cmu.edu

INSIDE PING: From the laptop, I can 'ping 192.168.1.1' and the router 
responds.  From the BSD box, I ping the same address and get 'host is 
down'.

INSIDE SSH: From the laptop, 'ssh 192.168.1.1' gives connection refused 
(as expected) and 'ssh 192.168.1.2' gives 'no route to host'.  But from 
the BSD box, 'ssh 192.168.1.1' gives 'host is down'.

I've tried switching network cables -- both work from the laptop, neither 
work from the BSD box.  I tried using xl0 (the card nominally used for the 
external internet) to connect to the internal network and got the same 
results.

All the routing and network config information looks sane.  I posted the 
output of the following commands at http://301south.net/~b/debug.net :

# netstat -rn    	(shows routing table)
# ifconfig		(shows interfaces)
# ipfstat -i		(shows IP filter input rules - allow all)
# ipfstat -o		(shows IP filter output rules - allow all)
# ipnat -l		(shows NAT table)
# kldstat		(nothing interesting)
# route get 192.168.1.1
# ping 192.168.1.1

(all as root).

I'm'a stumped.  Totally baffled.  Without recourse.  In response to Tom 
Rhodes' questions, yes bpf and miibus are both in the kernel.

I guess this will be my last post on the topic.  Next week I'm putting 
Linux on the box, if I can't get it working with BSD (my preferred 
choice).

Thanks for reading,
