I am thinking of moving from a dial up connection to ADSL. I currently have
4 Macs on network, 2 connected via an Airport (old airport with v1.3), and 2
via ethernet all connected through a hub with a printer also attached.
Internet connection is dial-up through the airport but I want to move to
ADSL.

The Airport network design manual says it should be no problem to move to an
ADSL set up by connecting the ethernet ADSL modem to the hub as well as the
Airport to the hub. Iprimus who I currently use won't comment and will only
provide a direct connection to one machine. Has anyone got any experience of
what I am trying to do. I don't want to apply for the ADSL connection and
find I can't use the same network set up to share the connection.

Assuming it will work should I upgrade to Airport software v2.0? Is there
any advantage in doing so?

The hub I currently have is a simple Netgear ethernet hub. I've seen that
there are also ethernet hubs through which you can share an internet
connection and which provide a firewall. Is this necessary or can I still
use my existing hub? Is Norton firewall running on the individual Macs
sufficient protection?

Does anyone have any experience of the ADSL service provided by iprimus? Are
there other ISP's that I should consider?

All help will be gratefully appreciated.

Many thanks in advance.
