Ok so when i ran a connection tes on my PS3 I get a Type 2 NAT, which from what I read is a "open" NAT.
When I load into Black Ops it tell me my NAT Type is moderate.
I read online that enabling UPnP can fix this, which it did. But I also read that using UPnP can create security holes.
Is this a true stament? Is UPnP safe to use? Is there a safer way to get a Open NAT type?
