For example, the PC has an ethernet card, a WIFI card and a Bluetooth
card (quite standart today).
- Ethernet is on 192.168.2.10
- WIFI is on 192.168.3.10
- Bluetooth is on 192.168.4.10

When the program running on the PC broadcasts a packet on Ethernet,
source address of the packet can be 192.168.2.10 or 192.168.3.10 or
192.168.4.10. I thought it would be 192.168.2.10 but this is not allways
the case.
    

Are you sure you want to send to 255.255.255.255 at all? Rather than
192.168.2.255 (assuming that is the subnet's broadcast address)?
  

Yes, I am sure. I am surprised it works this way but it is. Same thing with W2k
