Thanks, Andy.  The netmask was defaulting to 255.0.0.0 and I now
set it to 255.255.255.252 at each end.  I tried again without cu
and setting both ends as 10.0.5.1 and 10.0.5.2, but still had the
same behavior (can ping out, but no packets received or route to
DNS on the cient). The test server's network card is at 10.0.2.15
with the gateway at 10.0.2.2 and the DNS at 10.0.2.3.  Adding
additional static routes to those endpoints through the NetBSD
server did not seem to help.
