Make sure that your "ifconfig en0" in /etc/rc.boot contains both a
broadcast address and a netmask in this case, set in the order listed
below.  If I remember correctly, this should fix your problem (I've
done too much since the last conversion and details are slipping).

Anyway, the ifconfig I'm using is below.  The broadcast address for
a network or subnet is the net number with a host part of all 1's
(i.e. my network is 128.210.7, my broadcast is 128.210.7.255).  A host
part of all 0's used to be used on Berkeley hosts, but they have since
fixed that.  Using a host part of all 0's on the NeXT means that the NeXT
won't recieve its broadcast packets.

 	/usr/etc/ifconfig en0 $INETADDR broadcast 128.210.7.255 netmask 0xffffff00 -trailers up	>/dev/console 2>&1
