(summary) Booting diskless from different subnet

The following does reflect that proxyarp is the answer to my
question but as the kernel is finishing the boot my 3/50 hangs.
It hangs after the following:

hostname: ruby
domainname: .cs.clemson.edu
root on ypmaster-gw:/export/root/ruby fstype nfs
swap on ypmaster-gw:/export/swap/ruby nfs size 16384K
dump on ypmaster-gw:/export/swap/ruby nfs

I am not sure what is supposed to happen next but would assume /etc/rc
is supposed to get started. Packets are still getting through to the
ypmaster-gw but nothing else happens. If you don;t have a theory on
whats wrong I know someone has to know what the next occurences in the
booting sequence is.

Here is a summary of my original question:

This is a summary of the answers I received.

Use proxyarp. The message from dlc@LANL.GOV best explains it.
