hi everybody, 

i have trouble configuring a netbsd-6.0.1-amd64 using a hostroute to an 
out-of-network gateway with a /32 "network". since this is a hosted server, i 
cannot influence the network config in any way. The machine also does not want 
to boot at all unless i disable ACPI (-2). the config is 
X.Y.132.210/255.255.255.255 via X.Y.128.1 (where X and Y are constant), which 
is applied using: 

# ifconfig wm0 inet X.Y.132.210 netmask 255.255.255.255 up
# route add -host X.Y.128.1 -link wm0 -iface -expire 1
# route add default X.Y.128.1 -ifp wm0

i know that the upstream router is the next hop, so -expire 1 should be OK. 
leaving it out does not change the behaviour. all commands return without 
errors, just that i cannot get any v4 traffic in or out of the machine. tcpdump 
does not show anything. the same happens when using 6.1-RC1 and -current.

am i missing something obvious or is it supposed to work? i need help at this 
point.

attached are text files with ping, ifconfig, netstat and dmesg outputs.

thanks in advance, 
   flo
