I'm at a loss

Seriously....

We just got connected at our bank with fiber optics, and for the most part it is sweet. 0ms ping times between local offices, and the internet speeds are incredible.
But here is the challenge...when we route everything through our Sonicwall Pro 3060, all of the internet slows down to 1.5 up and down. I have it on the X2 WAN interface, no bandwidth management is enabled, and the MTU is set at 1500.
Now when I connect my sandbox to the fiber directly, this is what I get:

Now I have checked everything on this firewall that I can think of, but still nothing. Does anyone have experience with this model of Sonicwall and a fiber connection?

Thanks
 
I personally prefer a Cisco ASA or Juniper NetScreen. From my experience, the sonicwalls really bog down when there are a lot of security functions turned on.

I need some more information about your topology.

Some questions:
Did you buy a 3rd party fiber->ethernet transceiver to plug into the sonicwall or does it have a native fiber interface?
What type/model of device is connected to the sonicwall inside interface? Does this device have a native fiber interface?
Can you check logs anywhere? Check queues on the interfaces? Is it dropping packets at a massive rate?

Some suggestions:
1. Try something else besides a speed test.
2. Set the speed/duplex manually on your X2 WAN port. Maybe it's not negotiating properly.
3. Turn off some of the security features of the sonicwall to see if that improves your speed at all.
4. Try to test the internet connection through your entire network, except leave the sonicwall out. Don't just connect the internet directly to a computer (if possible).

I realize that some of these might be hard to do at a bank, but maybe you can schedule some down time.

Click to expand...

Topology:
Fiber in from ISP ->Term shelf ->fiber media converter (converted to copper at this point) ->Extreme Summit 400-24t switch ->Sonicwall Pro 3060 -> Dell 2748 Gig Switch

The sonicwall was set to auto negotiate, I have set it to 100 full, but still the same. Logs reveal nothing. I came in early and setup another test network with a different firewall, and all worked great, so something on the firewall is causing this. So I'm still at square one, and still chipping away....
