But here it all works fine. I don't have any added firewall in place and used the Cnet Networking forum sticky (the top post) for the router settings. In short these are:
1. Router defaults.
2. Do not hide the SSID.
3. Test and if it works, move to WPA security, re-test.
That's it!

I have one PS3 game, LittleBigPlanet, that I've been having trouble connecting to other players with on many occasions. I've done much research on the issue and people say it's most likely either a firewall issue or the NAT type of the router. My NAT type is 2, but I've also read that 1 or 2 will work fine. However, when connecting the PS3 to the network over Wifi I get a message saying the router may not support IP fragments and the communications features of some games may be restricted. Could this be the issue in itself? This is what I'm trying to figure out. But for the time being, I'm just focusing on the firewall.
At the time I started to have this problem, the PS3 was fully firewall covered; no port forwarding was enabled for it, although uPnP was. I began to change some things around, starting with giving them system a static IP address and opening certain ports (on both protocol types) used by the PlayStation Network for online games. After doing that, I checked them with www.ping.eu, but the IP address it detects is different from what I assigned to the PS3. What's that all about? I tried both IPs and checked the ports but none of them were open. I then tried common ports like 25 and 80, but they're closed as well! What's going on, does the PS3's web browser not handle the scripting on the site correctly, giving false negatives? I also tried completely DMZ'ing the system (disabling port forwarding first of course) but that didn't change a thing.
I'm fairly new to all of this network stuff. I know some basic concepts of a network but need more experience with the details. Can someone help me with this? I'd most appreciate it.
