Does anyone know if a broadband internet cinnection can be shared over a firewire lan? or if it is even possible to create a local area netwrk using firewire cables when the firewire port is on my SB Audigy 2 ZS Audio soundcard?
Do you see a "1394 connection" in your network connection in Windows? If yes, then just share away. It doesn't matter what type of network you have as long as it supports TCP/IP.
1394 is 1394. sound card is just another way for it to connect to the mobo on the pc just like as if you'd buy a pci 1394 card or adapter etc.. to set up internet sharing just run networking wizard, and setup accordingly.
