Digitap...hope you got your ears on.  And anyone else who might be able to help.
 
I'm sure I'm missing something here, but I"m trying to setup Sonicwall TZ100 and Netopia 3347 (I believe model is the 3347NWG).  

I have put the Netopia router into bridge mode and have the SonicWall configured to do PPPoE.

On the WAN interface on the SonicWall I have it configured to "SPECIFY IP ADDRESS" with the IP address given to me by the ISP.

When I connect to internet, everything works OK EXCEPT:

The PUBLIC IP address given to me by AT&T is a dynamic IP address that changes each time I connect.

HELP please.  I eventually want to be able to setup VPN to the sonicwall.

I've done this before a while back and don't remember having to do IP Passthrough.  I know I need to disable NAT.  So, thanks so much for the instructions to that part..  What should the ip addresses be on the WAN and LAN interfaces?
if the ISP use dynamic IP, u have to set DHCP for your TZ100's WAN interface

So, you have a static IP from the ISP and you've configured the WAN to use PPPoE and you've statically configured the WAN IP, right?

What if you configure PPPoE on the sonicwall and let the ISP give you an IP rather than specifying it? Does it get the correct IP?

I would have thought that the ISP would have given us the static public Ip address they gave us (70.x.x.x).  BUT, when the sonicwall connects and authenticates, the ISP give us a 99.x.x.x ip address and it changes each time I disconnect and reconnect.  So it is dynamically assigning this IP.  

So, in the WAN configuration on the sonicwall, I configured it to connect PPPoe and at the bottom it has a place to "SPECIFY IP ADDRESS".  I put the 70.x.x.x ip address in there but it does nothing that I notice.  Ip address after connecting is still a 99.x.x.x ip address.

We were trying to set this solution up in our lab before taking it to another location.  It would not work in our lab.  Kept on getting dynamic assigned IP when WAN on SonicWall was logging in using PPPoE.  However, when we moved the solution to the other location, when the SonicWall logged in using PPPoE it was assigned the Static IP.  It also gave us the correct default gateway.  I guess you have to be on the assigned line in order to get the correct static IP address assigned.  Rookie mistake?

Oh, I didn't realize it was in a lab situation. I thought you were live. It's my understanding that in a PPPoE and static IP configuration, the ISP will assign the PPPoE device the proper IP. I think that was what our expectation was, in a production deployment of course. Anyway, glad you got it.

I did not specify the lab environment in my initial post.  Although Digitap did not realize this, he answered in his first post that made me realize that I should try the solution live onsite.  Once I did it worked.  Thanks!
