You can run the following from Windows XP and it should allow multicast UPNP (discovery) traffic, and port 5001 (PS3 -> PMS unicast traffic). I haven't tested this (as I said I don't use a firewall on my windows PC), but try them, and provide some feedback.
- Code: Select all
C:\>netsh firewall add portopening protocol = UDP port = 1900 name = UPNP mode = enable scope = custom addresses = 220.127.116.11/255.0.0.0,LocalSubnet
C:\>netsh firewall add portopening protocol = TCP port = 5001 name = PMS mode = enable scope = subnet
(the first line may wrap, but it is just one line).
Obviously, this won't help if you are using a 3rd party firewall.
