[ILUG] Information on setting up a home network

[Frank Duignan]

Don't know about the netopia modem but it *may* have several ethernet
ports.  If so then I suspect that it will do network address translation for
you.  failing that get yourself a wireless access point thingy with the
usual 4 port + 1 wan port and away you go (a straight switch will *NOT* do
address translation for you - which I presume you want).   These things
inevitably come with a web interface and are pretty simple.
