I will do that when I get home, but from memory it is 192.168.2.50 (I have just the built in 100BT port). I did edit the multicast from 192.168.1.255 to 192.168.2.255. The broadcast is left alone at 230.0.0.0.

The Rio Receiver is getting 192.168.2.14 from my DHCP server (POS SMC Firewall thing) - the PC is static.
