Dual Firewall Setup

Hey Peeps HELP HELP

I have some network experience but am not an expert!!

Here is what I'm after

I would like to have two firewalls for my network.
What I would like to do is set up a pc firewall running a software firewall
(netpatrol, black ice, norton etc)
so I can monitor internet and network traffic.

This is the structure of my network as it is now:

--DSL highspeed modem(router) RJ45 cables connected to wan on SMC Barricade
using DHCP then uplinked to 24 port d-link hub

Everything works fine. Internet and Network


My PC firewall is running win98se and has two nic cards a d-link nic and a
onboard sis nic.

How do I or can I setup this firewall between my SMC Barricade and my 24
port hub. I can see my network but cannot access the internet.
Could it possible be the type of cables i.e. straight-through or cross-over
or do I need to setup this firewall as a gateway or server??
OR do I have to change the physical location of the firewall ...after my
highspeed modem??

Thanks in Advance

Thomas

What make and model is your DSL highspeed modem(router)? If it runs
its own a built-in firewall function, no undesired Internet traffic
can get through it to your network in the first place.

For now, let's assume that your modem(router) lets undesired traffic
get through.

The Barricade's built-in firewall function blocks undesired Internet
traffic. With the modem(router) connected to the Barricade's WAN
port, even if undesired gets through the modem(router), you won't be
able to monitor that traffic on the firewall PC. The best that you'll
be able to do is to look at the Barricade's log file, if it has one.

To see all Internet traffic on the PC, connect the DSL modem(router)
directly to one of the PC's nic cards. Run a firewall program on the
PC to monitor Internet traffic and block undesired traffic.

To let the rest of the network access the Internet through that PC,
run an Internet sharing program. If you have Windows 98 Second
Edition, you can use its built-in Internet Connection Sharing program.
You'll have to make sure that the firewall program doesn't interfere
with the Internet sharing program.

You can connect the second nic to the wan port of the Barricade using
a crossover cable, then uplink the Barricade to the 24-port switch.
Make sure that the Internet sharing program uses a different IP
address range than the Barricade's LAN side.

However, if the firewall program is doing its job, there won't be any
undesired traffic getting through the PC to the Barricade.
