Can you perhaps just listen for all tcp traffic and not specify the src address and see what is on your network ?
I’d think you might try to listen for tcp src 192.168.0.0/24 dst not 192.168.0.0/24 and not specify any port. Or listen for all tcp traffic for at least 10 minutes and capture to a file, then transfer the pcap file back to your computer to analyze in the wireshark/ethereal gui later. If you could post a pcap file somewhere I’m sure folks will see if they can help determine the correct settings.
