Hi,

I have (what I believe to be) a routing question related to multicasting.

If I run my software on a QNX system that obtains it's IP address via DHCP multicasting works. However, if I run it on a
 QNX system that has a fixed IP address, it does not work.

I suspect this is because the system has no defined gateway. There effectively is no gateway in that configuratation as 
there are two computers on a subnet using fixed IP addresses.

The network configuration is pretty much the default except that I've assigned a static IP address.

What would I need to do to make this work?

Thanks in advance ....
