help with network setup

Hi,

I'm trying to design a really secure network which has both wireless
and ethernet and I was wondering if there is a common standard type
of network setup I should use.

I was thinking about something like this ...

Internet --> Firewall/Router(1) --> Access Point --> Firewall/Router(2)
--> Computers

The questions I'm wondering about are ...

1) Is it common to put 2 firewalls in a network? I did that to put
things like the access point and maybe some web servers in between,
kinda like *I think* a DMZ sort of setup

2) Is this correct to place the Access Point between these two
firewalls? My thinking here is that since I want all the data on my
ethernet to be secure, then the access point should not be on the
inside and users should come through the same front door as anyone else
(along w/ the normal authentication and authorization on the wifi).

Thanks

Folks,


I have BT Max ADSL a FritzBox 7140 VOIP router and a 2Wire 2700 HGV (aka BT Business Hub) router.

On my long line the 2wire router syncs @ 1900, much faster than the FritzBox (@ 800-900). This makes
a considerable difference to the download speed.

But I need the VOIP functionalty in the FritzBox.


Ideally what I would like to do is to use the 2Wire as a "dumb" modem, and the fritzbox as the NAT
router and VOIP box. And for the PC's on the network to use DHCP as normal.
But I dont understand how to do that.


My current understanding is that I can do this by placing the 2Wire in to "bridge" mode
Is that correct? (I am not sure what bridge mode is...)

When I select bridge mode the 2Wire wants me to enter an IP submask - what should I put in here?
Should I disable the 2Wire DHCP server?

I can disable the FritzBox DSL modem and get to to connect via the LAN1 port to the 2Wire.
Should I specify the FritzBox IP address? Or use DHCP? (which server - the 2Wire?)
What should the default gateway be?


Ay pointers gratefully received....
