At a minimum, you need a NIC for each machine. I'd get PCI NICs, since USB will typically become the bottleneck in your PC to PC connections. Besides, they tend to be less expensive. I presonally like 3com and Linksys KICs, but I'm sure lots of people will have other opinions. Before you network anything, make sure you're Anti-virus software is up to date. There's no excuse for falling victim to a virus that's been around for a while and for which there is protection.

You've got lots of options in terms of how you share the network. The easiest is to get an inexpensive hub/switch and share the connection that way. If you do that, you should run firewall software on each machine.

Another (preferable) alternative is to get a small office/home office router. Ths will provide an additional layer of security, as it will make it more difficult for others to get into your computers. You can get them with NAT (Network Address Translation) and/or SPI (Stateful Packet Inspection). With NAT, you have "private" IP addresses for your internal computers, but the rest of the world sees a single IP address. You can forward specifc ports to individual computers if you plan to run any kinds of servers (or do things like video conferencing). Otherwise, you can probably keep that turned off.

There are also more expensive fireawlls/routers that have a plethora of functions that you may or may not need. But if you're just doing casual surfing, they can be overkill.

hope this helps,

Mark

Another solution is to use an OLD computer and make a Linux router out of it.
You have plenty of choices here, from floppy based Linux routers, to ones with a hard drive and more functionality.

A.

Steve,

Steer away from the USB NICs (as well as USB ADSL/cable modems).  The simplest and most effective way is to get a Cable/DSL router (DLink is the cheapest I've found; I got my 4 port switch for about $65; LinkSys or NetGear work well, too) and take the Ethernet out of the back of your modem to the WAN or uplink port on your Cable/DSL router.  

The routers are very easy to configure (most come with a web page interface) that will allow you to specify your PPPOE settings (username/password).  They'll automatically reconnect you if your service is reset and will allow you a modicum of port blocking or forwarding.  If you want to get fancy, you can take the 1 public IP address your ISP is giving you, get dynamic DNS for it (think DynDNS.org) and configure your new router to forward port 80 requests to a PC running a webserver.  Cheap webhosting. :-)

Using components you already have, you could stick two NICs in one of your PCs and enable Windows 2000 ICS (Internet Connection Sharing).  It will serve DHCP to your other PC and allow you to get out to the internet.

The downside of this is that you *must* keep the PC acting as a proxy/firewall on whenever you want to get out to the internet.  If you reboot it or turn it off, you lose your connection.  So, if you're electricity conscious, you might want to use a small Cable/DSL router because they consume far less energy than a PC.

Regards,

Aaron

router modem best option then as modem holds connection and uses nat for local addresses.

two nics and cross over cable cheaper option,run pppoe on both pcs and connection share (run isp disk on both machines)
you can specify share files and file and printer sharing
both machines can access different sites simultaniously
