You also have to configure your PS3. Make your router's IP address as your primary, and enable UPnP.
I need some additional help with this..
What do you mean by make the router IP as primary?
set the playstation IP as the router ip? rather than a network address given by the router
I just entered the mac and surrounding PCs into the "workgroup" domain so they can work together
the PS3 should pick that up
I just cannot find the MAC at all on the PS3. I am running Tiger 10.4.11 with iLife '08, and MediaLink is ON. It even shows the PS3 in devices section.
Firewall Log shows the following:
