I think that is the answer, limit the switch to have the cable modem,
plug computer and existing cable router on it. the "lan" side of that
cable router will be where I connect everything else and can use dhcp
with confidence there.
I presume nfs (which I have not used before) will still work connecting
the plug computer as an nfs client throught the router (which is a NAT
device) to one of the backend servers running a large disk and the nfs
server end if I port forward correctly. [one particular usage of my
external web site is to provide access to some large files - I am happy
for this to fail if I turn off my in home computing environment leaving
only the plug computer running.
