Right now, nuttcp udp tests are not supported, but I can’t remember why that 
limitation is in place. I’ll do some testing to see if it can be removed.

The -o parameter just tells the receiver to connect to the sender (normally 
the sending host connects to the receiving host) so it shouldn’t have any 
effect on the host.
