    The gateway is for both IBM and OBM. As long as IBM and OBM are different subnets, then the traffic will go out whichever interface is in the same subnet as the default gateway.

    If you find the gateway isn't working, please check with the route command from the debug> prompt. If you don't see the gateway programmed, please try resetting it, either from the CLI or by changing it and then changing it back from the web.

    From the debug prompt you can also try pinging the gateway or something on a remote subnet.

    Removing and reapplying the gateway fixed it you can see from my cmd output it was lacking the default route was able to get to gateway but no further. I reset the gateway back to default then to the right gw and all is well.

    Great! I believe the lost gateway is caused by changing the IP or IBM address after setting the gateway.

    As you can see in your second example, the default route shows. This should not be a problem unless the addresses are changed again.
