ipmi - can't ping or remotely connect
I've tried configuring the IPMI controller to accept remote connections, but I can't even ping it.
Here is its status:

In summary. It exists on the ARP list so arp's are being broadcast. I can't ping it and can't connect to it. Can anyone spot any glaring mistakes in the configuration?
Many thanks, Fidel
As other people already stated, it may be a networking problem. You are supposed to be able to ping the BMC by default.
However, it could also be a more insidious issue caused by the BMC not taking the new configuration in account.
Try to reset the BMC: mc reset cold
I have experienced this problem on many Dell IDRAC-stuffed machines, and the reset always fixed it.
In my experience it is necessary to set the default gateway MAC address in order to establish connectivity from the outside of your network. Also, if you are using link aggregation and have a shared port for the BMC, it brings other problems. On some switches it's possible to circumvent the load sharing algorithm for a MAC or IP address and direct the traffic to a specific port.
If your BMC shares the interface with the motherboard, make sure your network module is loaded with "CrcStripping=0".
