The router should take care of any WAN threat from an Internet source.
However I would also install Zone Alarm, as well as a virus scanner that
scans in the background, on each computer. This would add another layer of
protection from external attack, as well as protect you from email and user
introduced trojens and viruses.

\ As far as protecting them from the other LAN, I would like more
information. Is the router only used for this 3  PC LAN? Or are other
computers plugged into the router. Is this  going to be a Workgroup or
Domain ? Are the three PCs going to be sharing files, printers and
resources, or are they just sharing the router for Internet access ? Is the
Win2K machine going to be a file server? What is the File system on the
Win2K box. Is it NTFS ?  Are the 3 computers connected to any other
computers, or is this three everything?  If they are sharing files and
resources, are the files on one PC, or spread out on all three. what other
resources are shared and with who. Describe the LAN.
