Help...need to replace router in front of a Sonic Wall

Hi all,
This week my main BT router failed. This was a managed service at one time and i can't find any documentation about its configuration. The problem i have is that it sits between BT and a Sonic Wall firewall. The sonic has been configured with two internal networks (LAN and DMZ) ports being utilized.
I have just recieced a replacement router from BT, but its unconfigured and a completely different model.

I tried to re-configure the new router and could not get my network backonline, so i was wondering if you guys could give me some advice and how to re-configure the new router.

Some documentation i have is listed below

I have a non NAT service and the range assigned to me is:

217.37.143.40 to 217.37.143.48

Firewall External Ethernet address 217.37.143.41
Firewall Internal Ethernet address 10.20.128.1
Firewall Internal Ethernet address 10.20.130.1
Firewall NAT entries 0

I also have been using windows VPN (pptp) to the following address for server1 and server2
Server 1 VPN dial address 217.37.143.44 (internal network 10.20.128.1)
Server 2 VPN dial address 217.37.143.43 (internal network 10.20.130.1)

The Sonicwall WAN interface show this configuration:
217.37.143.41
255.255.255.248
217.37.143.46 (default gateway)

So i plugged in my new BT wireless HUB unit and went to set up the internet connection and just can't get it to work. I know the internet connection is good because if i use DHCP to get an address i do. Trouble is i need to set this with manual addreses the way the old router was in order to get things up and running again.

Would really appreciate any advice on this one..

Hi,

I am not sure at all because I miss some info but lets try this...

When you receive your configuration on the BT with DHCP take note of the default gateway.

Then configure manually the configuration

IP: 217.37.143.46
mask : 255.255.255.248
gateway (the same from the DHCP)

Hi Thanks for you comment,
I must be just rubbish at routing...i seem to understand the theory. I just want
to understand how to put a router such as a zyxel in front of a sonic will.
I notice my zyxel has an option to use bridged mode...i'll give this a try and see what
i get.

Okies, i think i realise what i need to do. I received a router from BT and rang them. They informed me to add the sonic will to its DMZ which now allows traffic to pass to the sonic. However, i can no longer use VPN services as the bt router will not pass that apparently, which sucks.

I will have to buy a new router which i hope to just setup as a pass through router, that's what i really need to do...
