OK, I'm at a bit of a loss here.  I'm replacing an older sonicwall pro 3060 with standard OS to a NSA 4500 with the enhanced OS.  I've setup 3 interfaces, the LAN (which works fine) my WAN (which doesn't seem to work) and my DMZ (which I can access from my LAN but not from the internet)

Now, I've checked my WAN properties and my IP, subnet, dns etc are all the same as what's on my old unit.  I'm using the same LAN info as well, and just swapping out the units.  I have no trouble accessing the FW when i make the switch. I have link lights on mt WAN port (x1)

I've looked at my routes and can't seem to find anything wrong.  I do have a bunch of static routes, but all to either specific VLANs in the 192.168.x.xxx or in my DMZ and where copied by from my old router.  Granted the setups aren't the exact same between the routers.  Same goes with my access rules.

DMZ is in transparent mode and shows the same subnet as my WAN.

Any suggestions as to what to look at?

I have seen some internet modems be particular regarding the MAC address to which it is connected.
I think you can simulate a MAC address with a sonicwall.
Also, I belive the sonicwall has diagnostics that will enable you to ping your WAN gateway address, directly from the sonicwall. If this fails, try the MAC address thing, or contact your isp.

Maybe an issue with duplex (half/full). Try to set it to fixed.

i think it's the speed/duplex as caskrist has suggested already.  however, you might check your mtu.  if incorrect, you'd drop packets making it seem like you can't connect to the internet.  here's an article that walks you through that.

As an FYI, my router is a Cisco 2621XM.  I did do a MAC clone, didn't help.  I changed the MTU to what was on my previous router as well.  My link shows as 1000mbps full duplex.  Now I'm connected through an Fa0 port on my router, shouldn't that then be 100mbps?

I've also setup a bit of a test environment for this, - I've set the LAN IP to .2 from .1, and have given it an IP in my public range (this one is .104, instead of .66 as 104 was the only open IP I have currently).  My old sonic wall was connected to a hub then to my router, so I'm planning on plugging both into the hub.  Is there any reason this wouldn't work?   I'm switching my PC's gateway from one to the other.

Yes, the hub is an option. But try setting the wan interface to fixed 100 mbps fulle duplex.

Well I'm not 100% sure why, but it's seems to work (in the test environment above).  I changed it to force 100mbps, but that didn't seem to fix the issue.  I downloaded and installed the newest firmware, and BAM! it's up and running

if you are in a hub at the moment, then changing the speed/duplex MAY not resolve the issue.  however, if your WAN interface is connected directly to the cisco, then it would...at least in my experience.  i always have to set the static speed/duplex.

glad you got it with the firmware.
