I have been doing some work on implementing bootp for a couple of
programs I have, and have noticed something strange...  We have a couple
of XENIX and SUN boxes, and have a remote link (with PCRoute) to another
site.  If I set my gateway address to the IP address of a XENIX system,
and then ping the remote system, the XENIX system will reroute the echo
request to the PCRouter and all is well.   However, if I set the gateway
IP address to one of the SUNs, the echo request is not rerouted and
there is no response.  I've watched this happening with LANWatch, so I'm
pretty sure of the facts.  I have tried PCTCP and PCIP pings (as well as
my own) with the same results in each case.
 
Any ideas welcome.
