m0n0wall Forum - VMware installation troubles connecting to WAN

Hi, I have a Windows 2003 server setup as a DHCP server with two network cards, one 10/100 card connects to a Bigpond cable service using a Motorola SB5101 modem; the other a Gigabyte card connects the LAN which is assigned its IP addresses via the server in the 192.168.88.xxx range.

I installed VMware server and used the m0n0wall appliance to get up and running.

I can get m0n0wall to talk to the LAN but I am having trouble connecting to the WAN. I guess I am struggling with some concepts as networking is not my forte. Am I actually involved with WAN ? as the WAN nic is being virtualised m0n0wall is interacting with that virtual nic.

Vmware is setup viz:

VMnet0 - Gigabyte card.
VMnet1 - Vmware network adapter VMnet1. subnet 192.168.142.0
VMnet8 - Vmware network adapter VMnet8. subnet 192.168.80.0 DHCP 192.168.80.128 thru 254 NAT gateway 192.168.80.2
VMnet9 - 10/100 card.

When I run IPconfig using the NT command prompt I get

Gigabyte card. IP = 192.168.88.19, DNS server 192.168.88.19 DHCP enabled no
VMnet1 - 192.168.142.1 DHCP enabled no
VMnet8 - VMnet8. subnet 192.168.80.1 DHCP enabled no
10/100 card (WAN) 58.160.120.240, gateway 58.160.120.1, dhcp server 172.18.52.140, DNS 61.9.133.173

So now I try to configure m0n0wall to join my WAN with the LAN.
I set the IP address to 192.168.88.42
I set the WAN to Bigpond
On general setup the DNS servers is set to "ALLOW DNS server list to be overrridden...."

I can ping any address on the LAN but not on the internet. I am stuck on what to do next any guidance would be sincerely appreciated.. Cheesy
