Yup, online lobbies are broken for me too at the moment. 10 MBit/sec is more than enough. Most online games only transmit a couple of kilobytes per second. Latency and stability is what's important for online gaming, and that depends a lot on the technology the connection is based on, the quality of the network hardware used by your ISP, and the quality of the infrastructure between your ISP and whatever you're connecting to. Old telephone-cable-based DSL connection are mostly fine for online gaming. As for modem/router settings: make sure to enable UPnP - it's mostly enabled by default, but check anway. If that's enabled, all the port forwarding stuff gets automatically negotiated by your network hardware. But in this case it's obviously a problem at PD/Sony's end, not ours.
