With NIS 2005, I selected "Block" for Twonky (server and exe) and the connection between my PC and PS3 was fine.
I just tried to use Twonky for the first time since installing NIS 2009. It will not work blocked.
Now I could live with that, but why the heck won't it work when I set the rules to allow connection to AND from ALL computers on the local subnet using ANY protocol???
In other words, the ONLY way my Twonky will work with NIS 2009 is to allow full internet access - I personally have a large problem with being forced by one vendor to allow another vendor to snoop on my PC.
