Do you have a wired connection to your switch to pc but are you wireless from ps3 to your router? I think using wireless could be possible but also cause issues. My setup is modem router switch from switch hard wires to both pc and ps3. You may have to login to router and open ports there. You may have to open ports on your pc (which appear ok) hope this helps...
I tried forwarding the ports but the error still exists and I use wired connection.
