How to configure a sonicwall TZ200 to work with a Netgear DG834 ADSL Router

I was advised to purchase a TZ200 so i did, for blocking Social Networking sites etc for a small company. After attempting to set this up 2 days ago i still haven't got it up and running yet and i was pretty much stumped just how difficult i was finding it even after reading several articles on installation. Bassically all i need it for really is Internet content filtering. Anyway i will list in detail the office setup as best i can and would appreciate any help at all to move me in the right direction. My Subnetting skills are very poor so detailed information would be great - Thanks.

1x Netgear ADSL Router DG834 - ISP Demon and it assigns 1x static IP address for the company: DHCP is enabled on the router and NAT
Router public IP 192.168.0.1

1x 24 port Netgear switch that connects the 10x XP pro clients and Netgear Router.

1x Windows Server 2k3 acting as Domain controller and file server only
Server public IP 192.168.0.30 - all clients 192.168.0.2 - 192.168.0.11

How do i go about placing the firewall onto this setup? someone mentioned bridging the router but this means i need to make changes to the router which i dont think it supports. Is it possible to do without bridging?   Can anyone give details please

Thanks in advance

If this works you are my HERO!!! - will be going in shortly to have a crack

I just want this setup with as little fuss as possible i.e not having to go round changing all the internal client machines IP's

Just a quick one... do i have to enable DHCP on the Sonicwall and turn off DHCP on the Router or should i just leave it.

Thanks

Something else i forgot to mention, just want to make sure i have connected the equiptmnet correctly.

ADSL Router - 1x patch lead into the back of the Wan port on the sonicwall
Sonical Wall - 1 x patch lead running into the Netgear Switch

Is this correct?

Cheers

DHCP: I assume it should work as before. If you get problems, disable it on the Router and enable it on the SonicWALL LAN/X0 side.

Cabling: Correct so far - but make sure you use the *X0 Port* of the SonicWALL to connect to the internal Switch.

Ok thanks for your very kind information.
I take it that the Sonicwall's IP will e 192.168.0.100 as you instructed and i have to change all client gateways to point to this?

set this up as instructed but the WAN x1 port will not keep the settings.
Error message is Subnet on this lan overlaps with another interface!

Any ideas
thanks
Hofpad

No, the clients gateways stay the same (192.168.0.1) since the SonicWALL ist transparent.

You can avoid the overlap error when you first reset the box to factory defaults or change the LAN IPs to someting other like 10.10.10.x (dont forget to also change your management station to this network so you are still able to manage the sonicwall).

Did a reset on the sonicwall and started from fresh
Using a laptop with xp prof to configure
Patch cable from laptop to Lan port on Sonicwall and patch from sonicwall to Router

Lan X0 port to 192.168.168.168
Subnet 255.255.255.0
IP assignment Static

Wan X1 port = 192.168.0.100
Subnet 255.255.255.0

Default gateway = 192.168.0.1
Dns = 158.152.1.58   - from internet provider


Laptop ip address = 192.168.168.5
gateway 192.168.168.168
DHCP 192.168.168.168
dns 168.152.1.58
These are set to auto assign in windows

I can access the internet from the laptop fine when directly connected but all other users on the lan can not.  

I'm still not clear about assigning network objects!! This is what i did
Network - Address Objects - goto address objects - ADD - Named it - Zone = LAN - Type = Range and my scope was 192.168.168.1 - 192.168.168.169

I have patched the Lan port on the sonicwall to the switch to test all clients but no joy - do i need to change the client ip address's

Cheers againi

This is not working and i have followed your instructions exactly as you descibed them.  I can not login to the address 192.168.0.100 either when the laptop is connected via the switch.  Is there any where i could look for a log report and maybe you will be able to guide me further.
Ive tried to call sonicwall 3x and it keeps cutting me off.

really appreciate your help
