To change tack a bit

We have 5 computers using Ishire for Internet connection which uses
NetBeui. as the protocol. We are using a ADSL modem at present
connected to one of the computer with ZApro as a firewall However, some
programs will not work well with Ishire and some not at all the program
was written in 1999, we are getting a hub
http://www.comsalnetworksecurity.com/adsl/draytek.php

Are we taking a step back in security as we will have to put TCP/IP on
all of the computer to access the hub. The hub has a built in firewall
however, would we be advised to place ZoneAlarms on each computer as
well

Thanks

Barrie,
