FYI. first vs last depends on host OS, and as I recall windows and linux differ.

Hm! I was not aware of that at all. Will verify and update the README.
 
2. mis-configured broadcast address

Both the .1 and .2 host must have the same broadcast address set.

As .1 and .2 are different networks, it actually depends on the structure.

Always: The broadcast addresses must match between the IOC host (receiving the broadcast) network configuration and the client (sending the broadcast) ADDR_LIST setting.
If the client host has a network interface into the IOC host network: The client host network configuration on that interface must also match.
If there is a switch between the two networks: The switch needs to be configured to forward "directed broadcasts".

Cheers,
~Ralph
