Yes, the two networks have different subnet masks.
I have 255.255.252.0 on eth0 and 255.255.255.0 on eth1.
I'm no expert on network configuration, does this setup make it a non-starter?
Thanks,
Graham

Actually that variable has no effect on the IOC server, it only applies to the CAS which is not (yet) used by the IOC code.

The IOC server binds to all the interfaces it can see; there's actually no way to change that with the current code. I wonder whether your problem is actually that the machines do not have the same subnet mask settings, and hence their broadcast addresses are different? On Unix systems 'ifconfig -a'
will print the broadcast address; you need to make sure that all systems are using the same address.
The output from running 'casr 1' from the IOC shell may also give some hints.
