I was trying not to put my PS3 in the DMZ, although it's there now because I created a MIP with all ports wide-open to the internet last night so I could do multi-player RB last night.
My firewall does not support uPnP. I also seem to remember having to turn it off for some reason...
I guess I should have specified, I need to know what ports need to be accessible INBOUND, not outbound. I found that if I block all inbound, I can't do type 2 and multi-player does not work.
I'm hoping 80 and 443 don't have to be open inbound, as I use those for something else and only have 1 IP available.
