Re: Home network setup

On Sunday 05 March 2006 6:13 pm, Trey Sizemore so eloquently stated:
My current home network consists of several PC connected to a Netgear
wireless router (using its default factory IP of 192.168.0.1). It also
serves DHCP address to machines that need it. It, in turn, is
connected to my DSL modem.

I will be adding a firewall to the mix and plan to use the Netgear
wireless router solely as a hub and WAP. I will disable it's DHCP
serving functionality.

My questions are:

a) Given it's new role, will it still require an IP address? If so, it
will be on my internal network (vs. DMZ with servers) and have an
address of 192.168.1.1 for example. Should this be changed now before
I rearrange the configuration? I assume it needs an IP as I will need
to access the web-based admin interface to turn wireless on and off,
etc.

I would just hook up the firewall machine between the modem and the router.
And yes, the router should still need the IP address, and I would continue to
use it as the DHCP server for your inside setup.

b) I would assume the WAN port would not be used and all machines
using the "hub" would just plug into one of the four LAN ports.
Don't do that, the router will get confused. And I am not sure if it can be
reconfigured. The router is wanting that port to be the link to the web, so
it knows where to route packages to.

c) I have a "true" hub that will be used in the DMZ consisting of
machines with addresses like 192.168.0.x. Here I assume the hub would
*not* have an IP assigned to it.
Exactly, hubs don't use IP addresses the way routers do. They also do not have
defined in and out ports.

Just to be clear, the firewall box has 3 NICs. One will have an IP
(dynamic) assigned by my ISP. The second will serve the DMZ and have
an IP of 192.168.0.1 and the third will serve the internal network and
have an address of 192.168.1.1.

Sounds like a good plan.
