It's a million times easier to just configure your PS3 to run as the DMZ on your LAN. If you have DHCP addressing in place, it's easy to do it. Then you won't need 52789 port forwards and triggering, etc. I actually have absolutely no port forwards in place on my router courtesy of using the PS3 as my DMZ. Why, do you ask? Because the PS3 has yet to be hacked from the outside. Being a Linux-based kernel it's already difficult, and because the operating system itself is unlike a normal home computer, the tools to do it are pretty much not applicable.
I noticed you turned off encryption....that's fine if the router is used for gaming ONLY. If you're using the router for everything in your house that's very very bad. I have multiple programs that I can use to not only sniff out network packets but I can also intercept Bluetooth signals and everything in between. This is how most people end up with neighbors stealing their internet or worse....identity theft. Not encrypting their transmissions and not changing their router's default user/password setting. Turning off your SSID broadcast and manually configuring all devices to access the node is the safest way to go.
Also, to the author....have you considered using DD-WRT firmware? Works great and has a lot more functionality than the default Linksys firmware. I'm using an older WRT54GL but runs like a $500 router thanks to the DD-WRT.
Not trying to step on your efforts in your original post. Just basing my feedback on the fact that I have two networking degrees (one of them in Information Systems Security). I have been providing help to PS3 users since launch on configuring their networks to run more smoothly and to achieve NAT2 status easily. Not that your suggestions won't work, I just like to provide the easiest solution for the less technically savvy folks out here.
when i do a speed test from my ps3 everything checks out fine but upnp comes up unavailable. Im wired and i have 14 mbps down speed and 1.3mbps up speed.
I download things fine from store and i can play online fine in killzone i just get disconnected after 2 map rotations is all sometimes. I think maybe this is the problem. I never get dropped while in game though (knock on wood ).
Im using at&t uverse so the router controls the house. Im not complaining at all about my internet speed though its fast. But should i be worried about upnp setting?
