Port forwarding with SBG900 and WRT54g2 and Vonage adaptor

Hi,
I am facing problem networking my 3 devices in the way I want.

Here is my setup.
1) Sbg900 Cable modem.
2) Linksys router WRT54g2
3) Vonage Voip adapter.(VDV21-VD)

Currently I have my network function with following configuration.

SGB900--> WRT54g2 --> Vonage adapter
--> Desktop PC - connected to WRT
--> laptop on wireless through WRT

This is all functioning properly.

My problem is that I am running a web server on my laptop and I want that to be exposed to the internet.So any of my buddies should be able to access my server from thier home.

I have tested this if router and Vonage are not in the setup.I simply opened port 80 in the modem firewall and It works fine.

However the issue is that I need to have both router and Vonage adapter in my setup.

Now SGB900 has both NAT and DHCP server.Also my router has a DHCP server.

I tried disabling NAT on sgb900 but then my laptop fails to get any ip address from my router.

I m not sure what I can do???

Thanks,
DS

Is the laptop connecting using SGB900 or the WRT54g2 802.11 WAP?

First, assign a static IP to your laptop -- on the same subnet as the rest of your LAN devices that hang off the WRT router, but outside of the range of addresses leased out by the router's DHCP server.

Then, administer port-forwarding on the WRT, forwarding port 80 to the static IP assigned to your laptop in the previous paragraph.

Leave the rest of the devices on your LAN (including your Vonage device) configured for DHCP.
