Assigning a public IP to a Sonicwall TZ 170

I am working on hosting a webserver on my private LAN. I have a 2Wire DSL modem, which connects me to my ISP. The 2Wire modem has a built in switch with DHCP and was assigned a public IP by my ISP, but it has built in NAT which converts the public IP to a private IP address pool. I have a Sonicwall TZ 170 which connects to the DSL modem's switch. I want to assign the Sonicwall a public IP address of 70.XXX.XX.XXX with a subnet mask of
My question is this: How can I assign a public to the Sonicwall that is on an entirly different network from the DHCP pool of the 2Wire modem?  How do I get the Sonicwall to access the internet if it's assigned a public IP?
Any help would be appreciated.

Did they provide you with the 2Wire? Do they manage it? If so, tell them you want to shut routing off on the thing and just want it to function as a bridge.
Short answer: You don't.

Long answer: If you can gain administrative access to the 2Wire unit (http://the_2wire's_ip_address/management), uncheck the "Enable Routing" box, and unit will function as an ADSL to Ethernet bridge. You will then have to configure the SonicWall to negotiate the connection to the ISP (using PPPoE, which you'll need the username/password for, or using DHCP to obtain an address from the ISP). Then you configure the SonicWALL to operate in NAT mode and use private addressing behind the SonicWALL.

However, you still won't be able to use a static IP address of your own choosing, even if you do this. Where did you get the address you want to use from?

OK.  My ISP provided me with 5 usuable public IP addresses. I want to assign one of those addresses to my Sonicwall. I don't have many rights to my 2Wire. What should I do????

Yes, that was my next step. They provided me with it and I don't have the rights to turn the routing and NAT function off.
