Our Machines :
	Nixdorf Targon/35 (Pyramid)	TOS 3.2.00 , NSP 3.2.01
	SUN 3				SunOS 4.0
	SIEMENS PC			SINIX 2.0, SINIX 5.?
All on a single Ethernet, but we are using class A adresses.

We had a similar problem with `rwhod' until we changed our broadcast-address :
( from /etc/rc.local : )

# TODO:  Define any machine host and network names here,  
#        then check the "ifconfig" commands.
ENET0=$HOST
# ENET1=${HOST}-alt
BROAD0=89.00.00.00
# BROAD1=altnet-broad
NETMASK0=0xff000000
# NETMASK1=0xffffff00

We don't use the routed, and we never tested it, but try exchanging '00's and
'ff's in your broadcast-addresses.
Also the ".254." in your subnet-address looks a bit strange to me.
