Here's a device that basically does just that:

About $60 US he

"Stateful Packet Inspection".

You want to post a link to any NAT-router (ethernet or otherwise) that
does packet inspection and costs less than $500?

Does Best Buy, Circuit City, CompUSA, etc, sell them?

I've seen Netgear, D-Link, Linksys Ethernet routers with SPI at CompUSA for in the
neighborhood of $100 US.

I never thought to check whether you could still find these modem devices,
though of course, other areas of the world WOULD require or offer them. Less
of a market here, as Americans move to the other access types. Thanks Glen
for the links.

Even in North America you would be surprised as to how many folks are
still on dial up. Here are a few more firewall appliances that can be
used with analogue modems:

You're NOT going to be able to connect more than two computers together
with just category 5 cables and NICs. Even with just two computers you
would need a special type of cable called a crossover cable between the
two NIC cards. To put a third computer in the system you would NEED a
hub between the computers. A switch connects the LAN (Local area
Network) to the broadband connection. A router is actually a hub and
switch combined in the same unit. Wireless routers add a third function,
called a wireless access point, to the hub/switch combination.

I have seen new wireless routers for as little as $40 US.

After reading all of the replies, I believe it is time I went broadband;; I
will do it, its just that my 'octopus.net' (optus) has offered me a lousy
deal, but unfortunately its the only one I can afford.

All replies were read, and all links were kept, many thanks to all.

You're NOT going to be able to connect more than two computers together
with just category 5 cables and NICs.

Even with just two computers you would need a special type of cable
called a crossover cable between the two NIC cards.

Upper case = pure color
Lower case = white + color
Colors O G L B = Orange Green bLue Brown

oOgLlGbB ------ oOgLlGbB = "normal" cable
oOgLlGbB ------ gGobBOLl = "crossover" cable

To put a third computer in the system you would NEED a
hub between the computers. A switch connects the LAN (Local area
Network) to the broadband connection. A router is actually a hub and
switch combined in the same unit. Wireless routers add a third function,
called a wireless access point, to the hub/switch combination.

Mmmmh.... not quite correct.

A hub is almost just a knot tying all the cables together; all packet
traffic travels on all cables all the time. Hubs were cheap and
standard in the 10Mb Ethernet days

A switch adds some low-level logic to packet traffic, so that it
travels only on the cables between the computers it is from and to.
Switches used to cost more than hubs in the 10Mb days, but are cheap
and standard in today's 100Mb Ethernet.

A router adds a far higher level of complexity, at a higher level in
the network stack. Whereas switch logic is right down at the Ethernet
level, thus working with any network protocol (e.g. TCP/IP, NetBEUI,
IPX, proprietary), a router works at the network protocol level, which
today means TCP/IP. A router looks at IP addresses in packet traffic
and "knows" which packets are to travel within the Local Area Network
and which are to go "outside" via a gateway to other networks.


So a router has an "inside" for your LAN, and an "outside" for the
WAN, which often is the Internet. A pure Ethernet router has an
Ethernet socket on the WAN side, which connects to another server, or
a broadband device such as cable or ADSL.

An ADSL "modem" is just that; it converts ADSL traffic to a form a
single device can understand and use. It may connect via USB or
Ethernet, and the device that uses it is directly connected to the
Internet. It is up to that device to route traffic to other computers
in the LAN, if there is a LAN that is.

Better is to get an ADSL router, which combines the "modem" with a
router so that it becomes the device connected to the Internet. It
can then pass traffic to other computers on the LAN.

ADSL routers may have 1 Ethernet socket (now rare), or more typically
4 Ethernet sockets. These can be extended by connecting them to
Ethernet hubs or switches, so that more computers can use the same
Internet connection. In addition, a modern router may also have a
WiFi facility, so that computers can connect to the LAN via Ethernet
or WiFi. That ups the risk, so I prefer to avoid using WiFi.

A router can do more than simply route traffic; it can act as a
firewall, and can act as a DHCP server, i.e. passing IP addresses
localized to the LAN to whatever computers connect to it. This
conversion between Internet-wide addresses and localized addresses is
called Native Address Translation (NAT) and is a good protection
against direct Internet network attacks.

However, it is possible (though bad choice of settings) to hobble a
router so that acts merely as a Bridge between computers and the
Internet. Computers are then directly exposed to Internet traffic
that is unsolicited at the machine level.

A PC can act as a router, using the Windows ICS (Internet Connection
Sharing) facility or similar. Win98SE and later can act as ICS host;
any Win9x or later can act as an ICS client. In Windows, the ICS host
is always seen as 192.168.0.1 within the LAN, and it can assign IP
addresses to other systems via DHCP.

Thanks mister quirke.....
Your below post has certainly filled some Q marks my brain
was trying to deal with.
Sometimes its easier to understand things when read via a newsgroup
poster as opposed to reading a tech book.
