Nat type 2

Hello everyone,

Im new to this forum so hi . Anyway im struggeling with this problem for a very very long time now. The problem is that i just cant get a nat type 2 or nat type 1 on mij PS3, i tried everything. I did all the toturials on youtube and the internet that i could find but nothing works. I will give a quick update from my routers so that you guys maybe be able to help me!

The main device or something is an KPN Experia box (downstairs) witch sends a signal to another router via an ethernet cable, the router is an lynksis wireless-g broadband router 2.4ghrz 54mbps. Im always connected to the lynksis device.

Im sorry for the bad english (im Dutch) and if this thread is in the wrong subforum im sorry for that too.
