Unable to connect to IPMI with gateway configured

Hi,

We have a problem with a new 5230 appliance that we are installing.  When the IPMI is configured with a proper gateway we are able to connect to it, but when it has a gateway of itself configured it responds to ping and can open it in browser.

Here's the setup:

Appliance IPMI IP set to: 10.10.10.2

Laptop IP set to: 10.10.10.3

Gateway set to: 10.10.10.1

This is all connected via a simple 1GB hub, nothing fancy.  In the above config, I am unable to connect to the IPMI.

When I set the IP on the IPMI to 10.10.10.2, I am able to ping and browse the applaince.

What simple thing is it that I'm missing as to why it won't work when the appliance gateway is configured to what it needs to be in order to be on the network?

Thanks in advance.
